Summary:The disclosure provides a cleaning blade having a blade portion. The blade portion has a blade tip equipped with an edge constituted by a ridge line between the tip surface the blade portion and a blade surface arranged near a photosensitive drum. The blade portion satisfies the following expressions: a≤50 μm, and 0.1≤b/a≤0.6 where, when the blade portion is viewed along blade longitudinal direction with the edge in sliding contact with the photosensitive drum for measurement rotating in one direction, a represents a maximum amplitude of the edge which vibrates with the rotation of the photosensitive drum for measurement, and b represents a maximum amplitude when a position separated from the edge by 200 μm on the blade surface of the blade tip vibrates with the oscillation of the edge.
