Abstract
An image forming apparatus having a voltage generating circuit for generating a bias voltage which is supplied to a developing unit upon reception of a discharge voltage from the charger, for charging a photosensitive drum, based on the discharge voltage. The voltage generating circuit is controlled by a timing signal supplied from the CPU, so that the bias voltage is applied to the developing unit when the photosensitive drum rotates by a predetermined angle and is set at a position where development is carried out.
