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