    摘要: An image forming apparatus includes a controller including a primary heating control portion to control a heater to perform a primary heating to heat a fixing rotator with a first amount of power determined based on a temperature of the fixing rotator, a secondary heating control portion to control the heater to perform a secondary heating to heat the fixing rotator with a preset second amount of power, and a switch portion to control the heater to switch between the primary heating and the secondary heating during an identical print job and to perform at least one of a primary switching from the primary heating to the secondary heating and a secondary switching from the secondary heating to the primary heating at a time different from a preset control cycle that defines a power supply time in the primary heating and the secondary heating.

    摘要: A belt including a first roller is supported by a plurality of rollers, and is driven to rotate in a predetermined direction. An abutting member makes contact with at least one edge of the belt in its width direction. A pressing member applies a pressure on an extended surface of the belt in its thickness direction at a position near a contact portion of the belt with the abutting member and on an upstream side of the contact portion in its moving direction.

    摘要: A process cartridge capable of lowering the line pressure of an abutment section of a layer thickness regulating member and thus reducing the stress on toner when the toner passes the abutment section. Toner adhering to the surface of a supply roller is supplied and applied to the surface of a development roller. The development roller is a roller covered with an elastic rubber layer and the elastic rubber layer is set to have a hardness which makes it possible to prevent toner degradation caused by a concentration of pressure exerted on an abutment section which abuts against a layer thickness regulating member. The surface roughness Ra is set at 0.3 to 2.0 μm, whereby the required amount of toner can be held by the surface. The resistance value of the elastic rubber layer is set at 103 to 1010Ω in consideration of the application of a development bias. The layer thickness regulating member is fixed to a development device in a state where the top of the layer thickness regulating member is inserted into the development device. A thin plate made of metal mainly such as SUS or phosphor bronze, or a thin plate subjected to bending process is employed as the layer thickness regulating member.

    摘要翻译: 一种处理盒,其能够降低层厚调节件的邻接部分的管线压力,从而当调色剂通过邻接部分时减小调色剂的应力。 粘附在供应辊表面的调色剂被供给并施加到显影辊的表面。 显影辊是覆盖有弹性橡胶层的辊,并且弹性橡胶层被设定为具有这样的硬度,该硬度使得可以防止由施加在邻接层厚限制构件的抵接部分上的压力集中引起的调色剂劣化 。 表面粗糙度Ra设定为0.3〜2.0μm,由此可以通过表面保持所需量的调色剂。 考虑到显影偏压的应用,弹性橡胶层的电阻值为103〜1010Ω。 在厚度调节部件的顶部插入显影装置的状态下,将层厚调节部件固定在显影装置上。 作为层厚调节部件,采用主要由SUS或磷青铜等金属制成的薄板或经受弯曲加工的薄板。
