Developing method in imaging-forming device

摘要

A developing method in an image-forming device is provided. The developing method includes the steps of charging a photoreceptor; exposing the photoreceptor to form a first latent image on the photoreceptor; developing the first latent image by a first developing unit having a first potential to form a first toner image; and discharging the photoreceptor having the first toner image, such that when the photoreceptor is charged again, the first toner image on the photoreceptor has a second potential, and the second potential is approximately the same as the first potential of the first developing unit.
