摘要： In the control of an electric power steering apparatus, where so-called lead steering control is performed in which a steering wheel angle signal is output through a lead filter to correct reaction delay of a driver and a vehicle, a delay in control response occurs due to feedback of a road surface reaction force torque. When road surface reaction force torque is fed back to the steering wheel, it is added through a low-pass filter having a time constant equal to a reaction delay time constant of a driver. A sum signal is output through a lead filter to a second motor for controlling a steering shaft.

摘要： In the control of an electric power steering apparatus, in the case where so-called lead steering control is performed in which a handle angle signal is outputted through a lead filter in order to correct a reaction delay of a driver and a vehicle, there has been a problem that a delay of control response occurs due to the feedback of a road surface reaction force torque. When a road surface reaction force torque SAT is fed back to a handle 105 and is added, it is added through a low-pass filter 202c having a time constant equal to a reaction delay time constant t1 of a driver. An added signal is outputted through a lead filter 202b to a second motor for controlling a steering shaft.

摘要： An electric power steering apparatus having a steering system capable of flexibly setting a relationship between a steering angle of a steering wheel and a wheel angle of a tire. The first motor controls steering reaction force exerted on the steering wheel. The on-center region determination section determines whether the steering wheel is in a position of an on-center region. The tire reaction force torque detection section detects tire reaction force torque transferred from the tire. The control section calculates a steering torque based on the tire reaction force torque and a torque gain. This torque is detected by the tire reaction force torque detection section. And the control section controls the first motor to exert the steering reaction force corresponding to the above calculated steering torque on the steering wheel. This control section also sets the torque gain in case of determining of on-center region larger than that in case of determining of non-on-center region.

摘要： An intermediate transfer belt and a photosensitive member form a transfer nip. An electrode is arranged close to an inner surface of the intermediate transfer belt in a portion on an upstream side of a direction of endless movement of the intermediate transfer belt with respect to a downstream-side exit of the transfer nip and on a downstream side of the direction of endless movement with respect to a position at which a transfer roller charges the intermediate transfer belt. A voltage of same polarity as the polarity of a toner is applied to the electrode, so that there is no movement of an electric charge between the electrode and the intermediate transfer belt.

摘要： A developing device for an image forming apparatus includes a developing roller for conveying toner deposited thereon to a developing region where it faces a photoconductive element. A magnet brush roller conveys a two-ingredient type developer, which consists of toner and magnetic particles, deposited thereto to a toner supplying region where it faces the developing roller. In the toner supplying region, only the toner is supplied from the magnet brush roller to the developing roller. The distribution of the number of toner particles for an amount of charge differs from the developing roller to the magnet brush roller.

摘要： A developing unit of the present invention includes a developing roller facing a photoconductive element and formed with a magnetic layer on its circumference. The magnetic layer has a plurality of magnetic poles of opposite polarities alternating with each other and each extending in the axial direction of the developing roller. A developer consisting of magnetic particles an toner are deposited on the developing roller by the magnetic poles and conveyed by the roller to the photoconductive element carrying a latent image thereon, thereby developing the latent image. An agitator for agitating the magnetic particles and toner is positioned relative to the developing roller such that a blade thereof has an agitation range overlapping with the magnetic force range of the magnet layer. With this configuration, it is possible to insure high quality images free from background contamination and toner scattering while extending the service life of the developing unit.
摘要翻译：本发明的显影单元包括面向感光元件的显影辊，并在其圆周上形成有磁性层。磁性层具有彼此交替的多个相反极性的磁极，并且各自在显影辊的轴向上延伸。由磁性颗粒构成的显影剂由调色剂通过磁极沉积在显影辊上，并被辊传送到在其上携带潜像的光电导元件，从而显影潜像。用于搅拌磁性颗粒和调色剂的搅拌器相对于显影辊定位，使得其叶片具有与磁体层的磁力范围重叠的搅拌范围。通过这种配置，可以确保高质量的图像免于背景污染和调色剂散射，同时延长显影单元的使用寿命。
