An image forming apparatus includes an image forming unit that forms an image on a recording medium and an image forming apparatus body in which the image forming unit is provided, and on which a first manual feeding tray and a second manual feeding tray having a configuration different from the first manual feeding tray are selectively mountable at a same mounting position.

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

An operation assisting tool includes a gripper, and an engagement portion to engage with a handle of a drawer drawable from a housing of an image forming apparatus.

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 accommodating device includes a device body, an accommodating unit that is movable to a supply position where a user is able to supply a medium by being pulled out from the device body in a pulling direction and of which a centroid position is located on one side surface side with respect to a center in an intersecting direction with the pulling direction, a first expanding and contracting member that expands and contracts to connect the accommodating unit to the device body so as to be able to be pulled out and is fixed to one side surface of the accommodating unit in the intersecting direction, and a second expanding and contracting member that expands and contracts to connect the accommodating unit to the device body so as to be able to be pulled out and is fixed at a position higher than the first expanding and contracting member on the other side surface of the accommodating unit in the intersecting direction.

An image forming apparatus includes a housing, a toner image forming portion, a foil transfer unit, a sheet tray, and a discharge portion. The toner image forming portion is provided in the housing and configured to form a toner image on a sheet. The foil transfer unit is configured to superpose a foil with a surface of the sheet. The sheet tray is installable in the housing in an inserting direction and configured to accommodate a sheet to be supplied to the toner image forming portion. The first discharge portion is configured to discharge the sheet from the foil transfer unit to the outside of the housing in a discharging direction opposite to the inserting direction. The second discharge portion is configured to discharge the sheet from the toner image forming portion to the outside of the housing without passing through the foil transfer unit in the discharge direction.

Example methods for cleaning a pick tire of a printer are disclosed, along with systems that may be used to carry out the disclosed methods. In an example, the method includes advancing print media from a print media storage tray with a pick tire disposed within a printer. In addition, the method includes stopping the advancement of the print media. Further, the method includes rotating the pick tire on the print media to clean the pick tire.

A sheet conveyance device includes a conveyance roller having first and second end portions in a rotation axis direction, an open bearing supporting the first end portion, a frame supporting the open bearing, and a second end support portion supporting the second end portion. The open bearing includes a roller support portion supporting the conveyance roller and an open portion allowing the conveyance roller to be removed through the open portion from the roller support portion in a direction perpendicular to a rotation axis. The open bearing is movable from a first position, at which the conveyance roller is restricted from moving, to a second position at which the conveyance roller can move in the rotation axis direction. The second end portion is removable from the second end support portion by moving the conveyance roller from the second toward first end portion with the open bearing at the second position.

A drive transmission device includes an intermediate gear, a housing portion, and a support portion. The intermediate gear meshes with a first gear and a second gear to transmit a rotational driving force from the first gear to the second gear. The housing portion is formed from resin and includes a pair of cover portions, covering both sides of a gear train including the intermediate gear, to house the gear train. The support portion is formed from metal and supports the rotation shaft of the intermediate gear at a position outside the housing portion.

An image forming apparatus is provided. The image forming apparatus for selectively feeding printing media to an image former of a main body through a cassette and a multipurpose tray includes a tray feeder configured to feed printing media placed in the multipurpose tray, a cassette feeder configured to feed printing media placed in the cassette, a power train configured to transmit power generated from a driving motor, and a power switching unit configured to transmit power transmitted to the power train to the tray feeder or the cassette feeder as the multipurpose tray is moved to a use position or a non-use position.
