Abstract
An image forming apparatus has a photoreceptor which has a radius of curvature of more than 35 mm at a transfer position or a separation position, a transfer roller provided at the transfer position where the transfer roller faces the photoreceptor, a transfer power supply source to supply a predetermined DC bias current onto the transfer roller, a conductive brush-shaped separation device provided at the separation position where the separation device faces the photoreceptor, and a separation power supply source to supply a variable DC bias voltage onto the separation device.
