Abstract
A cleaning device includes a thin plate-shaped first blade that cleans a surface of a toner carrying body by making a tip portion come in contact with the toner carrying body to carry toner. The first blade includes a substrate and a coat layer covering a surface of the substrate. In the first blade, a cross-sectional shape, in a thickness direction, of the tip portion is a convex shape, or a protruding shape in which a center side protrudes more than an end portion of a contact side.
