摘要： An image forming apparatus in which a toner image formed on an image bearing member is first transferred onto an intermediate transfer element and then onto a transfer member. A potential of the image bearing member is detected and a transfer bias voltage applied to the intermediate transfer element is controlled according to the potential of the image bearing member. Undesired images such as transfer blurring due to discharge at the first transfer area, and a solid image scattering and so-called crow's claw mark due to increase of resistance of the transfer member under low absolute humidities are improved.

摘要： An electrophotographic photoconductor comprises (a) an electroconductive support, (b) a photoconductive layer formed thereon comprising a selenium alloy, and (c) a protective layer which is formed on the photoconductive layer, contains a binder resin component and an anti-oxidizing agent. In an electrophotographic copying process and an electrophographic copying apparatus using this photoconductor, the protective layer is abraded at a predetermined rate during the copying process in such a fashion that the anti-oxidizing agent contained in the protective layer is always present at the surface of the protective layer, thereby protecting the photoconductor from ozone and ions which are generated during corona charging of the photoconductor.

摘要： An image forming apparatus of the type transferring a toner image from an image carrier to an intermediate transfer body by primary transfer, and transferring it from the intermediate transfer body to a recording medium by secondary transfer is disclosed. Before the primary transfer, a charge of the same polarity as the charge of the toner image is deposited on the intermediate transfer body. The charge deposited on the transfer body reduces the scattering or blurring of the toner image apt to occur when toners of different colors are superposed, without deteriorating the paper-free feature of the apparatus.
