摘要： An image forming apparatus includes a third link portion which is rotatably connected to said first link portion at a position between said first connecting portion and said first moving portion so that said first moving portion and said second moving portion are moved toward said drum unit by rotation of said first link portion about said first connecting portion as a rotation shaft and by rotation of said second link portion about said second connecting portion as a rotation shaft in interrelation with slide of said slidable portion, and which is rotatable relative to the apparatus main assembly. The third link portion is out of contact with the optical print head at a portion corresponding to an end portion on the optical print head side.

摘要： 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.

摘要： An image forming apparatus includes a main assembly, a photosensitive drum, an optical print head, a receiving portion, a portion-to-be-engaged, and a guiding portion. The guiding portion is provided between the portion-to-be-engaged and the receiving portion with an interval from both the portion-to-be-engaged and the receiving portion. The guiding portion guides movement of a cleaning member in a direction from the receiving portion toward the portion-to-be-engaged while limiting movement of the cleaning member in a direction different from the longitudinal direction of the cleaning member to engage the engaging portion with the portion-to-be-engaged.

摘要： An image forming apparatus, including: a cartridge including a photosensitive drum and a regulation portion; a light emitting device configured to emit light from a light emission surface to the photosensitive drum; and a movement unit configured to reciprocate the light emitting device between an exposure position and a retracted position, wherein the regulation portion regulates a cleaning member, which includes a cleaning portion configured to rub and clean the light emission surface by a sliding movement of the cleaning member on the light emission surface of the light emitting device positioned at the retracted position so as to prevent the cleaning member from contacting the photosensitive drum and so as to bias the cleaning portion to prevent the cleaning portion from being separated from the light emission surface during the sliding movement of the cleaning member.

摘要： A cleaning rod includes a rod-like member, a slidable portion which is provided on a free end side of the rod-like member with respect to a direction in which the cleaning rod is inserted and which is slidable on a light emergent surface of a lens of an image forming apparatus, and a restricting portion configured to restrict movement of the slidable portion in a direction away from the light emergent surface with respect to an optical axis direction by contacting the holder at each of free ends of opposing wall portions of a holder of the image forming apparatus from a side opposite from a side where a photosensitive member of the image forming apparatus is provided with respect to the optical axis direction in a state in which the slidable portion contacts the light emergent surface.

摘要： 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.
