摘要： An image forming apparatus includes an image bearing member for bearing a developer image, a transfer member for electrostatically transferring the developer image onto a transfer material, a power supply for applying a voltage to the transfer member, and an electric current detector for detecting a value of an electric current which flows to the transfer member when the voltage is applied from the power supply to the transfer member. The image forming apparatus controls an output of the power supply by varying the voltage applied to the transfer member by a predetermined voltage quantity in such a manner that the electric current value detected by the electric current detector becomes a target electric current value. The predetermined voltage quantity can be varied.

摘要： A process is provided for making a fluoroplastic molded-in insert without any supplementary production steps. A predetermined number of polytetrafluoroethylene bearers support a core material apart from the surface of a mold by a space equal to the desired thickness of a surfacing material to be formed on the surface of the core material. After disposing the bearers between a mold surface and the core material, hot-melt fluoroplastics are molded so as to combine the core material, the bearers and the hot-melt fluoroplastics into one unit. As a result, the core material is completely and simultaneously embedded when hot-melt fluoroplastics are molded.
