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： An image forming apparatus includes an image holding member for forming a toner image, and a transfer roller for transferring the toner image formed on the image holding member onto a recording paper sheet. The absolute value of (.DELTA. log R)/.DELTA.V[(log .OMEGA.)/kV] representing the voltage dependence of resistance R of the transfer roller is set not more than 0.5. The contacting portion of the transfer roller and an intermediate belt can be uniformly discharged, and therefore intermediate belt can be prevented from being changed in its property. As a result, an image forming apparatus having a stable transfer characteristic can be provided.

摘要： Developer material remaining on an image bearing member after transfer are collected by a developer. A cleaning member is arranged between a charger and an exposure in contact with the image bearing member, for collecting the residual developer material. A bias controller controls biases to be applied to a cleaner, a charger, and a developer. During an image forming process, the biases are so determined that the residual toner on the image bearing member is collected by the cleaner. While the image forming process is not performed, the biases are so determined that the collected toner is removed from the cleaner to the image bearing member and then collected by the developer.
