Abstract
An apparatus includes: an image carrier; a charger to uniformly charge a surface of the image carrier; an exposing unit to perform write scanning on the image carrier; a developing unit that includes a developer carrier carrying a developer including a toner and that is configured to perform a visible image process on an electrostatic latent image formed on the image carrier; and a transferor to transfer a toner image that has been subjected to the process onto a material. If length Lg of a non-image part directly before an image part in an image carrier moving direction has the relation ofLg≧π·Ds/(Vs/Vp),where Vp and Vs are circumferential velocities of the image carrier and the developer carrier and Ds is a diameter of the developer carrier, suppression of toner attachment on the material is controlled in a predetermined length from an image front end in the direction.
