Cleaning device, and image forming apparatus, process cartridge, and intermediate transfer unit each including the cleaning device
Abstract:
A cleaning device includes a laminated blade member including multiple layers made of materials different in permanent set value and a holding member to hold the blade member. The multiple layers include an edge layer formed of a material higher in permanent set value among the materials and a backing layer disposed against a distal surface of the edge layer. The laminated blade member includes a leading edge where an edge portion of the edge layer contacting a cleaning target is located and a trailing edge where the holding member supports the blade member. A ratio of a thickness of the edge layer to a thickness of the backing layer at the trailing end of the blade member is smaller than a ratio thereof at the leading edge of the blade member.
