Abstract
A cleaning device cleans off a toner from a surface of a member rotating in a first direction. The cleaning device includes a blade made of an elastic material including a tip portion with a slanting portion that is pressed against the surface in a second direction counter to the first direction. A supporter supports the blade. An angle between the slanting portion and a longitudinal direction of the blade is obtuse. The slanting portion is pressed against the surface at a surface pressure of 2.0 MPa or more.
