electrophotographic equipment

Abstract

Abstract PURPOSE:To execute optimum transfer control according to the moisture absorbing condition of paper which is a transfer member and to stabilize image quality by providing a control means for at least either of the exposure of an exposing means or the impressed voltage of a transfer device by the leak current flowing to the transfer member by the corona discharge of the transfer device. CONSTITUTION:The leak current passed to the transfer member 6 by the corona discharge of the transfer device 4 is detected via a paper carrying member 7. The control means of at least either of the means for controlling the exposure of the 2nd exposing device 15 installed between a developing device 3 and the transfer device 4 by the detected current and the means for controlling the impressed voltage of the transfer device 4 is provided. The always stable image quality is thereby obtd. even with any kind of paper, i.e., moisture absorptive paper, normally moist paper and further high-resistance paper.
