Abstract
An image forming apparatus comprises an intermediate transfer unit associated with a photoconductive medium. A first unit transfers a developed image on the photoconductive medium to the intermediate transfer unit such that an intermediate image on the intermediate transfer unit is formed. A second unit transfers the intermediate image from the intermediate transfer unit to a copy sheet such that a reproduced image on the copy sheet is formed. The intermediate transfer device of one aspect of the present invention comprises a surface layer of a mixture containing a friction reducing substance which reduces a coefficient of friction on the surface layer. The intermediate transfer device of another aspect of the present invention comprises a surface layer of a mixture containing a fluorocarbon polymer component and a secondary resin component which are compatible with each other, a visible developed color image being formed on the surface layer.
