Cartridge including restriction portions configured to be attachable to compression coil springs compressed to press a cleaning blade to an image bearing member

摘要

As a typical configuration of a cleaning device and an image forming apparatus according to the invention, the cleaning device includes a cleaning blade which cleans an image bearing member, a plurality of compression coil springs which apply a force from the cleaning blade to the image bearing member, and a plurality of bosses provided to fix the plurality of compression coil springs to a frame. The particular boss that attaches to one of the compression coil springs is selectable from the plurality of bosses, which are disposed at different positions. As a result, the abutting pressure of the cleaning blade to the image bearing member is adjustable by changing the boss to which a particular compression spring is attached.
