摘要： A cleaning blade includes a support and an elastic member with a flat shape. The elastic member has a secured end secured to the support and a free end. A ridgeline of the free end contacts a cleaning target to remove substances adhering to a surface of the cleaning target. The elastic member includes a base and a surface layer made of a cured product of a curable composition. The surface layer is disposed on at least a part of an opposite face disposed to oppose a downstream side of the cleaning target downstream from a contact portion of the elastic member with the cleaning target in a direction of movement of the cleaning target. A thickness of the surface layer progressively decreases toward the secured end along a cross section perpendicular to a longitudinal direction of the surface layer.
