Abstract
A housing accommodating a fur brush and a cleaning blade is pivoted to a position close to a photoconductive drum and at another position far from the photoconductive drum by positioning a positioning shaft. When the positioning shaft is slid for moving the positioning shaft away from a photoconductive drum, an operating member attached to the positioning shaft is put into contract with a pivoting lever to raise the pivoting lever away from the photoconductive drum. Since the pivoting lever is attached to a blade shaft, a cleaning blade attached to the blade shaft is pivoted away from the photoconductive drum.
