ABSTRACT:
A tray positioning mechanism S contacts one of a paper feed tray2and a main apparatus body as the paper feed tray2is attached to a tray receiver52, to restrict movement in an attaching direction of the paper feed tray2. The tray positioning mechanism S is attached to the other of the paper feed tray2and the main apparatus body. The tray positioning mechanism S includes a fixed member Sf fixed to the other of the paper feed tray2and the main apparatus body, and a contact member St having a contact portion Sh. The fixed member Sf and contact member St are relatively movably connected to each other. At least one of the fixed member Sf and the contact member St has a plurality of reaction force receiving surfaces Ss formed continuously for receiving a contact reaction force of the tray positioning mechanism S when the fixed member Sf and the contact member St are in contact with each other. The reaction force receiving surfaces Ss are switchable to an operative state to vary and adjust the position in the tray moving direction of the contact portion Sh. As a result, a paper feeder for an image forming apparatus is provided, which can prevent a deviation of an adjusted position by a simple operation to adjust an optical of an image.
