Abstract:
A cleaning blade, including: rectangular elastic body blade containing cured first-UV-curable resin at tip ridgeline portion thereof, brought into contact with surface of to-be-cleaned member, the cured first-UV-curable resin being formed by impregnating the tip ridgeline portion with the first-UV-curable resin, followed by curing, and depth of the elastic body blade impregnated with the first-UV-curable resin from edge surface thereof is 50 μm-150 μm, wherein the elastic body blade contains surface layer containing cured second-UV-curable resin at the edge surface, wherein load-displacement curve of Martens hardness thereof has inflection points, and is obtained by pressing region of the surface layer thereof via resin particles having average particle diameter of 5 μm-10 μm, and distance of the region from the tip ridgeline portion is 0.5 mm or less, and wherein ratio of displacement at the inflection point, with which load is maximum, to the average particle diameter is 1.5-2.0.
