Abstract: An image forming apparatus includes a photosensitive member that is rotatable, a substrate, a lens array, a holder, and a conductive member provided on the holder. The substrate includes a plurality of light-emitting elements, a driver integrated circuit (IC), and a wiring pattern. The plurality of light-emitting elements is arrayed in a rotational axis direction of the photosensitive member to emit light to which a surface of the photosensitive member is exposed. The driver IC drives the plurality of light-emitting elements. The wiring pattern includes a supply line that supplies power to the driver IC and a ground wire that grounds the driver IC. The lens array collects the light emitted from the plurality of light-emitting elements on the photosensitive member. The holder holds the substrate and the lens array, is grounded, and is made of metal. The conductive member electrically connects the holder and the ground wire.

Abstract: A cleaning member for use in an image forming apparatus and configured to be inserted into the apparatus, the apparatus comprising a holding body that holds a substrate and lenses, the cleaning member comprising a rod, a cleaning portion provided in the rod to clean a light emission surface of each lens, a magnet attached to the rod, the magnet emitting a magnetic field to generates a magnetic force to draw the holding body thereto so that the cleaning portion maintains contact with the light emission surface, a yoke member attached to the rod and in contact with the magnet. The yoke member is configured to protrude, with respect to the magnet, towards a side on which the holding body is disposed, and a contact portion that is configured to contact the holding body and that to protrude, with respect to the yoke member, towards the above side.

IPC: G03G15/04
Abstract: In a configuration in which a metal holder is supported by a resin member, the metal holder cannot be grounded, so that electricity may be discharged from the charged holder to a substrate held by the holder. The holder is provided with a pin to determine a position of the holder with respect to a photosensitive member. A conductive member that is made of metal and is grounded, is brought into contact with the pin to thereby enable the holder to be grounded through the pin.
