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 charges toner by applying a voltage and supplies the 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 electrostatically attracted. In an electrophotographic apparatus provided with a transfer device for transferring images onto a recording medium, an electrically conductive guide member is provided with a guide surface that holds the recording medium to a transfer position between the transfer device and the photosensitive drum, and the guide member is electrically conductive. An electrophotographic apparatus characterized in that a power supply section is provided to apply a voltage having the same polarity as the charged polarity of the toner to the guide 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 unit and the photosensitive drum is smaller than the absolute value of the potential difference between the voltage applied to the developing device and the photosensitive drum. .
