Abstract

A cleaning bladeincludes an elastic bodythat is a molded body of a rubber base material, and which has at least a surface treatment layerin a portion of the elastic body, the portion coming into contact with an object to be contacted. The surface treatment layeris formed by impregnating a surface portion of the elastic bodywith a surface treatment liquid, which contains an isocyanate compound and an organic solvent, and curing the surface treatment liquid; the surface treatment layerhas an elastic modulus of 95 MPa or less; the elastic bodyhas an elastic modulus of from 20 MPa to 60 MPa (inclusive); and the difference between the elastic modulus of the surface treatment layerand the elastic modulus of the elastic bodyis 1 MPa or more.
