Abstract
An image forming device includes a photosensitive member, a charger, an exposing unit, a developing unit and a control unit. The charger charges the photosensitive member, and the exposing unit exposes the photosensitive member to light and forms an electrostatic latent image on the photosensitive member. The developing unit develops the electrostatic latent image formed and has a developing member having a surface potential and developer charged to a polarity. The control unit applies a first voltage having a first absolute value to the charger at least during development while applying a second voltage having a second absolute value to the charger during operations other than development. The first voltage, the second voltage and the surface potential have the same polarity as the developer with the first voltage absolute value being greater than the second voltage absolute value which is greater than an absolute value of the surface potential.
