摘要： A photoreceptor unit is inserted into an image forming apparatus in the predetermined insertion direction, and includes a photoreceptor, a light-shielding sheet covering a part of the photoreceptor on the front side in the insertion direction; a rigid cover made of resin and provided adjacent to the light-shielding sheet on the rear side in the insertion direction; and a cushioning member interposed between the rigid cover and the photoreceptor. The rigid cover has a length that allows the photoreceptor unit to be gripped at the rigid cover. The light-shielding sheet, the rigid cover and the cushioning member can be removed together from the photoreceptor.

摘要： A first shutter covers a first supply port formed in an outer peripheral surface of a main body, and can move in an outer peripheral direction along the outer peripheral surface of the main body. A pair of guiding members respectively formed on both ends of the first shutter guide the first shutter in the outer peripheral direction. A lock mechanism fixes the first shutter to achieve a closed sate of the first supply port. The lock mechanism includes a protrusion provided to the first shutter, the protrusion being capable of engaging with a recess formed in the outer peripheral surface. Fixing by the lock mechanism is released when the protrusion elastically deforms and is disengaged from the recess. The protrusion, the recess, and the first supply port are disposed along a virtual curve between the pair of guiding members.

摘要： A belt fixing system for fixing a toner image to a sheet includes an endless belt. This belt is rotatably supported by a plurality of supporting members, or rollers. Also, the belt is heated by a heater such as lamp and rotated around the supporting members by a drive member such as motor. When a toner fixing has finished, the heater is switched off and then after a predetermined time period the drive member is halted. Preferably, the time period is a time required for the belt to make two revolutions. This approach prevents the belt from being heated too much, which extends the durability of the belt.

摘要： In a transport pipe having a first opening portion through which toner is fed in from a toner hopper and a second opening portion through which the toner is discharged to a development device, a transport screw in which a helical blade is formed on a rotational shaft is rotatably provided. The width of the first opening portion in the direction of the rotational shaft is greater than the pitch (L0) of the blade at the first opening portion, and, at the downstream end of the first opening portion in the transport direction, the pitch of the blade is switched from the pitch (L0) to a pitch (L1) which is narrower than the pitch (L0). In this way, the amount of transport of the toner from the toner hopper to the development device with the transport screw is stabilized.

摘要： A fixing apparatus includes a fixing belt that pressure-thermally fixes unfixed toner images on sheets, and an oil coating roller that holds silicone oil for preventing the offset phenomenon to be coated on the fixing belt. The oil coating roller consists of an inner oil holding layer formed of paper and a surface oil holding layer formed of aramid fibers. The oil diffusing capacity and the oil holding capacity are reduced from the inner oil holding layer toward the surface oil holding layer. Thus, it is possible to suppress the oil coating amount in the initial period of the roller life to a level that does not cause problems such as oil stains, increase the oil coating amount in the final period of the roller life to a level that does not cause problems such as offsets, and prevent image noises.
