    摘要: An intermediate transfer member is formed by at least a base layer and a surface layer. The base layer is formed by epichlorohydrin rubber and acrylonitrile-butadiene rubber mixed in a certain weight ratio (preferably 1:9 to 9:1). The surface layer is formed by urethane resin or elastomer and a fluorine-containing compound powder. The fluorine-containing compound powder may preferably be contained in an amount of 20-80 wt. % based on the surface layer. The intermediate transfer member is suitable for full-color image formation by electrophotography and is effective in improving a transfer performance and providing clear images without causing transfer failure even in repetitive use for a long period.

The intermediate transfer member is set to have a reflectance of 10-70% for light having a wavelength in the range of 700-1500 nm at least in a region thereof for forming the prescribed pattern. As a result, the pattern density detection is suitably performed on the intermediate transfer member for all of yellow, magenta cyan and black, and the detected density data is used for controlling the image forming conditions.
