摘要： An image forming apparatus of the present invention includes a charging device made up of a charge roller and a roller cleaning member for cleaning the charge roller. The charge roller is held in contact with a photoconductive element and uniformly charges the element while being driven by the element. The roller cleaning member is held in contact with the charge roller in order to remove impurities from the roller. The charge roller has a resistance ranging from 1.times.10.sup.3 .OMEGA. to 1.times.10.sup.7 .OMEGA.. The cleaning device exhibits a stable charging ability over a long time of use without resorting to a mechanism for moving the charge roller into and out of contact with the photoconductive element or for moving the roller cleaning member into and out of contact with the charge roller.

摘要： An image forming apparatus including a photoconductive drum, a charging roller which is held in pressured contact with the photoconductive drum, and a holder which holds a spreading blade having a free or unsupported end which is held in contact with the charging roller to spread toner and other particles which adhere to the surface of the charging roller. Preferably, there is a thin flexible film between the holder and the spreading blade. The spreading blade is held by the holder such that when the charging roller rotates, a frictional force pulls the spreading blade relative to the holder. This frictional force imposes a rotational moment on the spreading blade which reduces the force of the spreading blade against the charging roller when the charging roller rotates. In order to extend the life of the spreading blade and to achieve a uniform distribution of the particles on the charge roller, the spreading blade may be moved in a reciprocating motion along a plane tangential to the surface of the roller and/or along the length of the roller. The spreading blade spreads the toner and other particles which adhere to the surface of the charging roller into a thin uniform layer so that the charging roller uniformly charges the photoconductive drum.
摘要翻译：一种图像形成装置，包括感光鼓，与感光鼓保持压力接触的充电辊，以及保持器，其保持具有自由或未支撑端的扩展刀片，该扩展刀片与充电辊保持接触以扩散调色剂，附着在充电辊表面的其他颗粒。优选地，在保持器和扩展刀片之间存在薄的柔性膜。扩展刀片由保持器保持，使得当充电辊旋转时，摩擦力相对于保持器拉动扩展刀片。这种摩擦力在扩展刀片上施加旋转力矩，当充电辊旋转时，该力矩减小了扩展刀片抵靠充电辊的力。为了延长扩展刀片的寿命并且实现粒子在充电辊上的均匀分布，扩展刀片可以沿着与辊表面相切的平面和/或沿长度的往复运动移动的辊子。扩散刀将附着在充电辊表面上的调色剂和其它颗粒分散成均匀的薄层，使充电辊对感光鼓均匀充电。

摘要： A method, apparatus, and program for driving a motor in a feedback control system, capable of suppressing oscillation of the motor are disclosed. A motor drive controller includes a drive motor, a detector, and a motor drive controller. The drive motor drives a moving body around a target moving speed. The detector detects a current moving speed of the moving body and output it as a detector pulse signal. The controller calculates a difference between the current moving speed and the target moving speed, calculates a control value based on the difference, calculates a pulse rate of a drive pulse signal based on the control value after having controlled the control value to be within a predetermined value, and feedback controls the drive motor based on the pulse rate.
