A sheet processing apparatus arranged in a space between an image reading section for reading an image and an image formation section for forming an image on a sheet includes a carry-in path guiding a sheet from a carry-in entrance; a relay roller provided in the carry-in path to relay and transport the sheet; a first transport path positioned on a downstream side of the relay roller and having a carry-in roller to transport the sheet from the carry-in path to the first collection tray; and a second transport path branched from the carry-in path and having a branch roller to transport the transported sheet to the second collection tray. The relay roller shifts the sheet in a direction crossing the transport direction while a front end of the sheet enters the first transport path or the second transport path, and arrives at the carry-in roller or the branch roller.

In accordance with an embodiment, an electric apparatus is provided with a connection device configured to connect with an external power supply, a battery and a plurality of power load sections, and a controller programmed to select a supply destination of power of the external power supply from a plurality of the power load sections, and supply power of the battery to another power load section except the supply destination according to supply capacity of the external power supply connected with the connection device.

A controller is configured to execute a larger gamut technology mode in which the controller performs image formation by controlling a ratio of a rotation speed of a development roller to a rotation speed of a photosensitive drum such that the ratio becomes a second speed ratio higher than a first speed ratio in a normal mode. The controller is configured to, when the controller executes the larger gamut technology mode, control transfer voltage based on a humidity around an image forming apparatus.

A housing includes at least one openable cover and at least one adjacent cover. The at least one openable cover swings on a hinge to separate an interior of the housing from an exterior of the housing. The at least one openable cover has a first side edge on a side of the hinge. The at least one adjacent cover is adjacent to the at least one openable cover. The at least one adjacent cover has a second side edge neighboring the first side edge of the at least one openable cover across a gap. One of the at least one openable cover and the at least one adjacent cover includes at least one projection projecting into the gap and another one of the at least one openable cover and the at least one adjacent cover includes a recess that accommodates the at least one projection in the gap.

An electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus wherein a streak-like image defect otherwise occurring in output in a low printing mode performed under a H/H environment can be reduced are provided. A surface of the photosensitive member has a convex and concave portions continuously in a peripheral direction of the photosensitive member, and alternately in an axial direction of the photosensitive member, a width w of the concave portion is 30 to 100 μm, a depth d of the concave portion is 1 to 5 μm, the convex portion has a rising slope and a descending slope in the peripheral direction of the photosensitive member, and a distance from a starting point of the rising slope to an end point of the descending slope and a distance from a starting point of the descending slope to an end point of the rising slope are 300 μm or less.

An imaging system includes a toner imaging device to form a toner image, a toner image conveying device to convey the toner image, a medium conveying device to convey a medium, and a toner image recording device to record the toner image conveyed by the toner image conveying device on the medium conveyed by the medium conveying device. Additionally, the imaging system includes a control device to determine a stop state including at least one of a state where a recording check toner image is recorded on the medium, a state where a conveyance check toner image is positioned on the toner image conveying device, and a state where a formation check toner image is positioned on the toner imaging device. During the stop state, the control device stops a formation of the toner image that is performed by the toner imaging device, stops a conveyance of the toner image that is performed by the toner image conveying device, and stops a conveyance of the medium that is performed by the medium conveying device.

An image forming apparatus determines, in a first mode, an image forming condition according to characteristic data, which is input by a user and represents characteristics of a sheet contained in a sheet container, causes the sensor to detect characteristics of a sheet, and stores characteristic data according to a result of the detection into the memory. The image forming apparatus determines, in a second mode with the characteristic data being stored in the memory, an image forming condition, based on the characteristic data stored in the memory before a result of detecting a characteristic of a sheet by the sensor is obtained. The image forming apparatus causes, in the second mode with the characteristic data being not stored in the memory, the sensor to detect characteristics of a sheet, and determines an image forming condition based on a result of the detection.

There is provided a manufacturing method of manufacturing a cartridge by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end fixed to the elastic member and the other end abutting on the rotator along the rotation axis direction of the rotator, and the manufacturing method includes: detaching the rotator from the frame; detaching the sheet member from the frame; detaching the elastic member from the frame; and attaching another sheet member to the frame via an adhesive member that is attached to an adhesive member attachment portion formed in the concave portion of the frame.

An image forming apparatus receives a print setting for image data, determines a density correction table to be applied to a position of a pixel in the image data based on the received print setting from among a plurality of stored density correction tables, and corrects a density of the image data using the determined density correction table.

An image forming apparatus includes, an image forming portion configured to form a toner image on a sheet using printing toner and apply powder adhesive on the sheet, a fixing portion configured to heat the toner image formed on the sheet and the powder adhesive applied on the sheet by the image forming portion and fix the toner image and the powder adhesive to the sheet, and a bonding portion configured to bond the sheet with the powder adhesive by reheating the sheet having been heated by the fixing portion. The bonding portion is arranged above the image forming portion.
