Image forming apparatus having a function to charge a photoreceptor drum at an appropriate potential |
摘要 |
An image forming apparatus with which the surface potential of the photoreceptor drum is made appropriate reliably in a relatively short time is provided with the following: a charger unit for charging the surface of the photoreceptor drum; an exposing unit for forming a latent image; a potential sensor for detecting a charge potential; and a controller for controlling outputs of the charger unit and the exposing unit. The surface potential of the photoreceptor drum is made appropriate by detecting and correcting the potential after the photoreceptor drum surface is charged at a potential close to a desired potential. After both the dark and bright portions are charged at appropriate potentials, image formation is performed.
