摘要： A roller control device is provided that both sets sheets for printing and feeds them into an electrophotographic apparatus. The roller control device is may be constructed using a pickup roller that is mounted on a central axle and is used for feeding sheets of paper from a paper tray into an electrophotographic apparatus. A disk may be installed on the central axle between the pickup gear and the pickup roller. A solenoid may be mounted to the housing of the apparatus underneath the disk to modulate the movement of the disk using a latch that is interposed between the disk and the solenoid. A cam is installed on the central axle between the disk and the pickup roller to slidably contact a lift plate to set sheets of paper. The roller control device is usable in a compact apparatus, is economical to manufacture, and is easy to repair and maintain.

摘要： A method and apparatus for removing remaining toner from an image forming apparatus, when a non developing time is detected during a performing of printing, a supply voltage applied to a supplying roller is increased to a level higher than a developing voltage applied to a developing roller. When the supplying roller having the supplying voltage of a voltage level higher than the developing voltage is in contact with the developing roller, electric flux is directed from the supplying voltage having a high electric potential to the developing voltage having a low electric potential due to a difference of intensities of electric fields between the supplying roller and the developing roller, while toner having negative charge moves from the developing roller to the supplying roller in a reverse direction to that of the direction of the electric flux to remove the remaining toner.
摘要翻译：一种用于从图像形成装置去除剩余调色剂的方法和装置，当在执行打印期间检测到非显影时间时，施加到供应辊的供应电压增加到高于施加到显影辊的显影电压的水平。当具有高于显影电压的电压电平的供电电压的供给辊与显影辊接触时，由于具有高电位的供电电压而导致电流低于由于与负电荷的调色剂反向旋转，从而从显影辊向供给辊移动与电流方向相反的方向，从而除去剩余的调色剂，供给辊与显影辊之间的电场强度差异。
