A medium transport apparatus includes: a frame; a table including a placement surface on which a medium is placed, a first end portion, and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface; a first rotor arranged adjacent to the first end portion of the table; a second rotor arranged adjacent to the second end portion of the table; a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion; and a biasing part that links the frame and an attachment part provided between the second end portion and the first end portion of the table, and that biases the table.

A document conveying apparatus is provided with a document tray and a discharge tray disposed below the document tray. The document tray includes an upper tray member, a lower tray member, a movable tray member, and a driving portion configured to move the upper tray member and the movable tray member integrally to a raised position and a lowered position. The movable tray member is configured to be moved in a width direction between a first position and a second position in which the movable tray member is retracted into below the upper tray member. The document tray includes a shutter configured to cover a gap created between the upper tray member and the lower tray member. The gap is created by the upper tray member and the movable tray member being moved to the raised position and the movable tray member being moved to the second position.

A mounting member to be mounted on a member that moves in a traveling direction includes: a rectangular sheet member; and an attachment portion having a first surface bonded to one end portion of a reverse surface of a downstream side portion of the sheet member in the traveling direction, the attachment portion being detachably attached to an attachment-receiving portion and having a surface facing a direction different from a direction of the first surface and bonded to the sheet member.

An image forming apparatus includes: an image former, a paper feed tray that feeds a sheet to the image former; a display that displays a list of tray information on the paper feed tray, based on a mounting order with respect to an apparatus; and a controller that controls display of the display. The controller changes a display order of a list of the tray information according to a display priority based on an image forming operation.
