An object of the present disclosure is to provide a conveyance apparatus whose detection unit of a printing medium is unlikely to be damaged. One embodiment of the present invention is a conveyance apparatus including: a first guide that is fixed to a main body; a second guide capable of moving to a position at which the second guide forms, together with the first guide, a conveyance path through which a printing medium is conveyed and a position at which the second guide opens the conveyance path; a first lever that is provided to the main body and which detects whether or not the printing medium exists in the conveyance path; and a second lever that shields light, wherein the first lever and the second lever can swing integrally or independently in accordance with the position of the second guide.

An image forming system including a printer that forms an image on a sheet and an inspection apparatus that inspects an image on a sheet delivered from the printer. A discharge mode for discharging a sheet inspected by the inspection apparatus and binding processing for binding a plurality of sheets as one bundle are set on a console panel. In a case where a first mode for discharging a first sheet determined as normal by the inspection apparatus to a first discharge destination, discharging a second sheet determined as defective by the inspection apparatus to a second discharge destination different from the first discharge destination, and discharging a third sheet conveyed subsequently to the second sheet, determined as normal by the inspection apparatus, to the first discharge destination is set as the discharge mode, and the binding processing is set, execution of the corresponding job is stopped.

An image reading apparatus including: a conveyance path; a light transmitting member; a first reading unit; a second reading unit; a first roller disposed opposite to the first reading unit; a second roller disposed opposite to the second reading unit; a holding member configured to hold the first roller and the second roller; a plurality of first abutment portions provided on both end portion sides in a width direction of the first roller and forming a gap between the light transmitting member and the first roller by abutting on the light transmitting member; a plurality of second abutment portions provided on both end portion sides in the width direction of the second roller and forming a gap between the light transmitting member and the second roller by abutting on the light transmitting member; and an urging member urges the holding member against the light transmitting member.

A sheet binding processing apparatus includes a conveying portion, a conveying path for sheets, a stacking portion on which sheets from the conveying path are stacked, a first regulating portion for regulating a sheet bundle on the stacking portion in a crossing direction, a second regulating portion for regulating a sheet bundle in the conveying direction, a manual setting portion for setting sheets from an outside of the apparatus, and a binding device which binds a sheet bundle by a staple and moves in the crossing direction. An angular posture of the binding device located at a third position is different from an angular posture located at a first position. An angular posture of the binding device located at the third position is different from an angular posture located at a second position. The second position is located at a second side of the first position.

A developing cartridge includes: a developing roller; a coupling for rotating the developing roller; a shaft; and a clutch. The developing roller is rotatable about a first axis extending in an axial direction. The coupling is rotatable about a second axis extending in the axial direction. The shaft rotatably supports the coupling. The clutch is rotatable together with the coupling about the shaft in a case where the coupling rotates in a first rotational direction. In a case where the coupling rotates in a second rotational direction opposite to the first rotational direction, the clutch engages with a portion of the shaft and the clutch and the coupling do not rotate.

A sheet stacking apparatus includes a sheet stacking unit on which sheets are stacked, a sheet regulating unit, and a cover member. The sheet regulating unit includes a main body having a regulating surface regulating a position of the sheet on the sheet stacking unit, and an operating portion movably supported on the main body and having an operating surface. The operating portion is movable from a first to a second position by operating the operating surface. The sheet regulating unit is locked to the sheet stacking unit when the operating portion is in the first position, and unlocked when in the second position. The cover member includes a first surface covering the operating surface and a second surface covering an upper surface of the operating portion, and covers the operating portion with at least the first surface and the second surface so that the operating portion is not visible.

In an authenticity determination system, an image forming apparatus acquires apparatus identification information for identifying the image forming apparatus from a memory of the image forming apparatus, and consumables container identification information for identifying a container of predetermined consumables from the container of the consumables mounted in the image forming apparatus. A server stores the apparatus identification information and the consumables container identification information in association with each other, receives the apparatus identification information and the consumables container identification information transmitted from the image forming apparatus, and determines whether the received apparatus identification information and the received consumables container identification information are stored in association with each other. When the information on the determination is affirmative, the image forming apparatus executes printing based on output source identification information including the apparatus identification information and the consumables container identification information on an output using the predetermined consumables.

Disclosed is an image forming apparatus that includes: a detecting unit configured to detect a user approaching the image forming apparatus; a communication unit configured to be capable of receiving the job from a mobile terminal via short-range wireless communication; and a controlling unit that controls a power supply such that electric power is supplied from the power supply to a first device and a second device in response to detection of the user by the detecting unit, and controls the power supply such that in response to designation of a job from the mobile terminal via the short-range wireless communication, the power supply continues supply of the electric power to the first device that is used for executing the designated job and the power supply stops supply of the electric power to the second device that is not used for executing the designated job.

A conveyance device includes a conveyance roller pair to convey a recording medium to an image reading position of an image reading unit. The conveyance roller pair includes a drive roller and a driven roller. The driven roller contacts the drive roller and rotates following the drive roller. The drive roller has a diameter satisfying a relation in which a detection mark on the recording medium is on a position away from a leading end of the recording medium by an integral multiple of a circumference of the drive roller in a conveyance direction of the recording medium.

A fixing apparatus according includes: a heater that includes a substrate, a heating element provided on the substrate, and an electrode provided on the substrate and electrically connected to the heating element; and a power supply member that includes a first member bonded or coupled to the electrode to supply power to the heating element and a second member bonded or coupled to an opposite surface of the first member to a surface, which is bonded or coupled to the electrode, of the first member, wherein the heater generates heat by power supplied via the power supply member, and an image formed on a recording material is heated by heat of the heater; and a liner expansion coefficient of the first member is different from a liner expansion coefficient of the second member.
