Image forming apparatus using intermediate transfer body

The image forming apparatus using an intermediate transfer body according to claim 3, wherein a sectional shape of the concavo-concave slots is one of a sine wave type, a saw blade wave type, a square wave type, or a trapezoidal type.

An image forming apparatus using an intermediate transfer body employing an electrophotographic process in which an electrostatic latent image is formed by an exposing device on a photosensitive body charged by a charger, a toner image is formed on the photosensitive body by a developing device on the basis of said electrostatic latent image, the toner image formed on said photosensitive body is primarily transferred to the intermediate transfer body, and thereafter a secondary transfer is provided on a transfer medium, and employing a cleanerless process, not provided with a cleaner, for cleaning a transferred remaining toner remained on said photosensitive body,

• wherein surface roughness RzD1 of said photosensitive body is set to 0.01 to 10 μm, and surface roughness RzD2 of said intermediate transfer body is set to 1 to 30 μm, with RzD1<RzD2,
• wherein concavo-convex slots approximately in parallel in a progressing direction of the intermediate transfer body are formed over at least all of an image preparing region of the surface of said intermediate transfer body, and
• wherein a concavo-convex period of the concavo-convex slots is smaller than a write emitting period of the exposing device.
