とを特徴とするクリーニング装置。 A cleaning device for removing residual toner on an image carrier includes a first cleaning member comprising a cleaning blade that comes into contact with the image carrier to scrape off the residual toner, and a first cleaning member that primarily rubs the image carrier. a second cleaning member consisting of a fur brush that scrapes off residual toner; a flicker that comes into pressure contact with the fur brush and knocks off the adhered toner; The cleaning device is provided with an elastic roller that presses against the carrier, and a static elimination electrode below the elastic roller that eliminates the charge of residual toner, wherein the overlapping length of the flicker biting into the fur brush in each radial direction is as described above. Is it large compared to the overlapping length of the image bearing member biting into the fur brush in each radial direction?
A cleaning device characterized in that it is formed so as to have a relationship that is at most equal.
