摘要： In a rotary type image developing apparatus that has a rotary rack accommodating a plurality of developer units and drives the rotary rack to rotate in a predetermined rotational direction so as to bring a targeted one of the developer units to a developing position, each developer unit includes a toner storage in which a first slope is disposed. As the rotary rack rotates, toner that remains upstream of a toner supply opening in a toner flowing direction in the toner storage is guided by a slope surface of the first slope, which enables the toner to be smoothly supplied to a developing chamber. Thus, even when the toner gets low, the toner can be efficiently supplied from the toner storage to the developing chamber with the aid of the first slope.

摘要： Applied voltage to the contact charging sheet 71 has been controlled in the following various ways: a) the voltage at the photosensitive layer 10 at a point of time whereat it has passed the contact charging sheet 71 is caused to interlock with grid voltage so as not to exceed predetermined voltage to be electrified by the Scorotron charger 2; b) the applied voltage is caused to interlock with the output from the transfer unit 5 so that there is no portion which reaches the Scorotron charger 2 while the potential polarity has been reversed at the transfer unit 5; c) reduction in the film thickness of the photosensitive layer 10 is corrected in consideration of the cumulative number of sheets for image formation; d) the size of printing sheet is added; e) at the time of termination, a portion of the photosensitive layer 10, into which current has flowed at the transfer unit 5, is caused to stop always after passing the contact charging sheet 71; f) the contact charging sheet 71 is cleaned by means of AC component; and g) the applied voltage is switched while formation of an electrostatic latent image and the like are not performed. Thereby, the surface potential at the photosensitive drum 1 is prevented from becoming ununiform.
摘要翻译：接触充电片71的施加电压已经以下列各种方式进行了控制：a）使感光层10在已经通过接触充电片71的时间点处的电压与电网电压互锁，使得不超过预定电压由Scorotron充电器2带电; b）使施加的电压与转印单元5的输出互锁，使得在转印单元5处的电位极性已经反转的情况下，没有到达Scorotron充电器2的部分; c）考虑到用于图像形成的片材的累积数量来校正感光层10的膜厚度的减小; d）添加打印纸的尺寸; e）在终止时，使电流在转印单元5处流动的感光层10的一部分在通过接触充电片71之后始终停止; f）接触充电片71通过AC部件清洁; 并且g）在不形成静电潜像等的情况下切换所施加的电压。由此，能够防止感光鼓1的表面电位变得不均匀。
