CLEANING DEVICE AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To obtain a long-life cleaning device capable of preventing toner accumulated in a cleaning container from coming close to an external opening part when the cleaning device is detached. SOLUTION: The cleaning container 14 is divided into a cleaning chamber 14A and a discarded toner accumulation chamber 14B, and the chamber 14A is communicated with the chamber 14B through a paper feeding opening part 41c of a certain height. The toner is sent to the opening part by a feed blade 19 and a check-valve 42 is installed so that the toner may not flow backward. Besides, a rib projection is installed projecting from the upper edge of the opening part higher than the rotating radius of the feed blade into the inside so that the toner may be smoothly guided to the opening part 41c.
