In an image forming apparatus, a tray having first and second receiving portions is configured to move between a first position, at which at least part of the tray is positioned inside an apparatus body, and a second position, at which the tray is outside the apparatus body. The tray in the first position allows a first recording medium to be conveyed from the first receiving portion. When the tray is in the first position, the second receiving portion is configured to move between a third position, which is at an upstream side relative to a first opening of the apparatus body in a second direction, and a fourth position, which is at a downstream side relative to the third position in the second direction. The second receiving portion at the third position allows a second recording medium to be conveyed from the second receiving portion in the second direction.

A sheet post-processing apparatus includes a first regulating device regulating a position of a sheet bundle, by contacting to an end part of the sheet bundle conveyed in a conveying direction by a conveying device and stacked on a stacking device in a direction intersecting with the conveying direction; a second regulating device regulating a position of the sheet bundle in the conveying direction, by contacting to an end part of the sheet bundle stacked on the stacking device in the conveying direction; a first binding device configured to move from one side to another side of the sheet post-processing apparatus and from the other side to the one side by moving in the intersecting direction, and configured to bind a corner part of the sheet bundle using a staple, and a second binding device configured to bind a corner part of the sheet bundle without a staple.

There is provided an image recording apparatus having a housing having a front wall and a rear wall, and a right wall and a left wall defining an internal space of the housing, a sheet roll holder configured to hold a sheet roll, a supporting member configured to support the sheet roll, the supporting member extending in an axial direction of the sheet roll and being supported by the sheet roll holder, a sheet conveyer arranged in an internal space of the housing, the sheet conveyer being configured to convey a sheet unwound from the sheet roll, and a recording device configured to record an image on the sheet unwound from the sheet roll and conveyed by the sheet conveyer. The sheet roll holder is configured to be slidable with respect to the housing so as to be detachable from and attachable to the housing.

An image forming apparatus includes: a sheet conveyance section configured to convey a long sheet along a sheet feeding path; and an image forming section configured to form an image on the long sheet conveyed by the sheet conveyance section, the sheet conveyance section including a conveyance unit that includes a first conveyance roller and a second conveyance roller for conveying the long sheet in a sandwiching manner, and is movable along a sheet conveyance direction in a state where the long sheet is conveyed through the sheet feeding path.

An inventive rubber composition contains a rubber component including EPDM, a peroxide crosslinking agent, a white filler, and not less than 0.1 part by mass of a quaternary ammonium salt based on 100 parts by mass of the rubber component. An inventive molded rubber product (1) is made from the rubber composition. Thus, the novel rubber composition containing the rubber component including the EPDM, the peroxide crosslinking agent and the white filler can be imparted with any desired color (e.g., a light color such as white or a non-black color) and can form a molded rubber product excellent in strain resistance properties and the like without inhibition of the crosslinking of the EPDM. The molded rubber product is produced by using the rubber composition.

An image forming apparatus and roller separation device are provided. The image forming apparatus including a main body having a print unit, a first paper feeding unit containing print paper and insertable in or pullable from the main body, a feed roller in the main body feeding the print paper from the first paper feeding unit to the print unit and comprising a driven roller contacting a driving roller, an elastic member applying an elastic force to the driven roller in a direction to contact the driving roller, a handle member in the main body movable to a first position and a second position, and a separation member connected to the handle member and switched to a normal position separated from the driven roller and a separation position separating the driven roller from the driving roller.

A recording material feeding device includes a stacking portion, a driving source, a holding member, a torque limiter for limiting transmission of a driving torque from the driving source to the stacking portion in a case that the driving source rotates in a state in which the holding member holds the position of the stacking portion; a storing portion for storing information on a holding state of the holding member; and a controller for controlling the driving source to rotate at a rotational speed slower when the information is information indicating that the holding member holds the position of the stacking portion than when the information is information indicating that the holding member does not hold the position of the stacking portion.

A sheet supply apparatus detachably attached to an image forming apparatus is configured to receive a drive force from the image apparatus to supply sheet to the image forming apparatus. The sheet supply apparatus includes a sheet supply tray, a sheet supply roller, a first transmission mechanism configured to transmit a drive force from the image forming apparatus to the sheet supply roller, a second transmission mechanism including an output member and configured to transmit a drive force supplied from the image forming apparatus to the output member, a clutch mechanism configured to intermittently transmit a drive force from the image forming apparatus to the second transmission mechanism, a latch member pivotable between a restriction position and an allowance position, a change cam, a sector gear, a rotational force applying member, an engaging member, a first engagement portion, a second engagement portion, and an electromagnetic solenoid.

A printing apparatus includes: a first blade that cuts a printing medium; a cutter motor; a drive gear that engages the first blade and is rotated by the cutter motor to drive the first blade; a rotator that rotates in conjunction with the drive gear; a photosensor that includes a light-receiving/emitting section including a light-emitting element and a light-receiving element and that includes a sensor substrate that outputs a first detection signal or a second direction signal in accordance with whether or not detection light emitted from the light-emitting element to the light-receiving element is blocked by the rotator; a first cutter frame that supports the photosensor; and a cover member that covers the sensor substrate between the cover member and the first cutter frame.
