Abstract
A cleaning device for use in an image forming apparatus which includes an image carrier, an image forming device to form a toner image on the image carrier, and a transferor to transfer the toner image from the image carrier onto a recording sheet, in which the cleaning device cleans a residual toner on the image carrier after transferring. The cleaning device includes a cleaning blade to scrape off the residual toner on a circumferential surface of the image carrier, a contacting member to bring a tip end of the cleaning blade into contact with the circumferential surface of the image carrier in a direction upstream of a moving direction of the image carrier when a cleaning operation of the blade is conducted, and a releasing member to release the tip end of the cleaning blade from the circumferential surface. The blade is made of an elastic member having a coefficient of dynamic friction between the blade and the image carrier of 0.15 to 0.4.
