Abstract
An image-forming apparatus, comprising: a rotatable photoreceptor; a charging device configured to charge a surface of the photoreceptor to be a target charge potential; an exposure device configured to expose a charged portion on the surface of the photoreceptor to form an electrostatic latent image; a developing device configured to develop the electrostatic latent image using toner to form a toner image; a transfer device configured to apply a transfer bias between the photoreceptor and a transfer member by applying an electrical potential of opposite polarity to the target charge potential to the transfer member facing the photoreceptor, and which transfers the toner image on the photoreceptor onto a body to be transferred by the transfer bias; a neutralization device configured to neutralize the surface of the photoreceptor by irradiating the surface with neutralization light after the transferring; and a pre-rotation device configured to perform a pre-rotation process.
