Abstract
A cleaning blade unit for removing residual toner from a photosensitive member includes a first arm which carries a blade, and a second arm which carries the first arm in an angularly movable manner and is pivotally mounted on a stationary member. Both of the arms are urged to move angularly in a direction to bring the forward edge of the blade into abutment against the photosensitive member. When the forward edge of the blade is resisted by residual toner, the forward edge is urged against the photosensitive member with an increased force, thus effectively achieving a removal of residual toner.
