請求項１記載の電子写真装置。[Claims for Utility Model Registration] 1. A charger that applies a voltage to a photosensitive drum to charge it, and an optical scanner that optically scans the circumferential surface of the charged photosensitive drum to form an electrostatic latent image; A developing device is provided that supplies charged toner to the circumferential surface of the photosensitive drum to develop the electrostatic latent image, and the toner image formed on the circumferential surface of the photosensitive drum is transferred onto a recording medium by electrostatic adsorption. In an electrophotographic apparatus of a reversal development type equipped with a transfer device, an electrically conductive guide member having a guide surface for holding the recording medium to a transfer position between the transfer device and the photosensitive drum is provided, and the guide An electrophotographic apparatus characterized in that a power supply section is provided for applying a voltage having a polarity opposite to the charging polarity of the toner to the member. 2. The electrophotographic apparatus according to claim 1, wherein the absolute value of the potential difference between the voltage applied to the guide member from the power supply section and the electrostatic latent image is smaller than the absolute value of the potential difference between the toner and the electrostatic latent image. .
