摘要： An image forming apparatus accommodates a developing bias power unit for applying a bias voltage to a developing sleeve confronting a photosensitive member. The developing bias power unit includes a DC power source, an electricity storage element interposed between the DC power source and the developing sleeve, and a controller for on-off controlling the DC power source. When an output of the DC power source is activated, the electricity storage element is electrically charged by an output voltage of the DC power source, and a first voltage is applied to the developing sleeve. In contrast, when the output of the DC power source is deactivated, a second voltage of reverse polarity is applied to the developing sleeve by electric charge held in the electricity storage element.

摘要： A copying apparatus in which a developing bias voltage to be applied to a developing sleeve by a power source is changed to adjust the density of a reproduced image, while the electric potential difference between the developing sleeve and a toner supply roller is kept constant. As a result, a density of toner on the developing sleeve is kept constant. Therefore, a development is effected under the condition in which the density of the toner is constant, so that the tone of the image of an original document is reproduced in a desired density.

摘要： An electrophotographic copying apparatus is capable of forming outline images. It comprises a first charging device, an exposing device, a second charging device and a developing device along a moving direction of a photoconductor. A sensor detects an amount of toner adhering to a reference image formed on the surface of the photoconductor. Supply of toner is controlled based on the detected amount. In an outline image forming mode, an amount of toner to be supplied is set to a value smaller than an amount in a standard image forming mode.
