    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.

    摘要翻译： 定影装置包括：定影带，其对片材上的未定影调色剂图像进行加热定影;以及涂油辊，其保持用于防止在定影带上涂布的胶印现象的硅油。 油涂布辊由纸形成的内部油保持层和由芳族聚酰胺纤维形成的表面油保持层组成。 油分散能力和保油能力从内油保持层向表面油保持层减少。 因此，可以将滚筒寿命的初始期间的油涂布量抑制到不会引起油渍等问题的程度，将辊寿命的最后期间的油涂布量增加到 不会产生偏移等问题，防止图像噪音。

    摘要： A belt fixing device of a type gripping and transporting a recording member bearing an unfixed toner image between an endless belt and a back-up member to fuse the unfixed toner image on the surface of the recording member and comprising a fixing/drive roller, heating/driven roller heated by a heater, a heated endless belt wound around the drive roller and driven roller, and a back-up member pressed against the drive roller through the endless belt. The belt fixing member is capable of transporting a recording member so as to cause the least damage possible, e.g., wrinkling and the like, to the recording member, and precisely maintaining the belt transport speed and transport member transport speed at a predetermined speed so as to produce excellent fixed images. The drive roller has a surface layer of elastic material which is treated by a polishing process along the exterior and in a direction opposite the direction of powered rotation of the drive roller.

    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 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.
