摘要:
An electrostatic latent image holder unit includes: first and second electrostatic latent image holders that have first and second functional layers, respectively, the first functional layer being different from the second functional layer in component ratio, and holds an electrostatic latent image on a surface thereof; a contact type charging unit that is in contact with the first electrostatic latent image holder to charge a surface of the first electrostatic latent image holders at a predetermined electric potential level; a non-contact type charging unit that are spaced from the second electrostatic latent image holder, and charge a surface of the second electrostatic latent image holder at a predetermined electric potential level; an exposure unit that exposes the first and second electrostatic latent image holders to form an electrostatic latent image; and a development unit that develops the first and second electrostatic latent image with toner to form a toner image.
