Abstract
An intermediate transfer element has at least one or more elastic layers and a toner releasing layer provided on the surface of the elastic layer and has a surface shape including minute projections up to 60 &mgr;m and at least 20 &mgr;m high. By providing the intermediate transfer element with such projections, easy separation with respect to a poorly separable recording medium, such as thin paper is achieved, and an image free from image defects, such as white speckles.
