摘要： Disclosed a cleaning apparatus including: a brush to remove an adhered matter adhered to a photoconductor drum; wherein the brush includes: a first brush portion which contacts an end portion of the photoconductor drum in an axial direction, which portions is on a circumferential surface of the photoconductor drum, and in which portion a conductive base substance is exposed; and a second brush portion which contacts only a photosensitive layer on the circumferential surface of the photoconductor drum, and an electric resistance value of the first brush portion is larger than that of the second brush when a bias current is applied.
