  • Cleaning blade
    Patent number: 10394180
    Abstract: A cleaning blade 1 includes an elastic body 11 that is a molded body of a rubber base material, and which has at least a surface treatment layer 12 in a portion of the elastic body 11, the portion coming into contact with an object to be contacted. The surface treatment layer 12 is formed by impregnating a surface portion of the elastic body 11 with a surface treatment liquid, which contains an isocyanate compound and an organic solvent, and curing the surface treatment liquid; the surface treatment layer 12 has an elastic modulus of 95 MPa or less; the elastic body 11 has an elastic modulus of from 20 MPa to 60 MPa (inclusive); and the difference between the elastic modulus of the surface treatment layer 12 and the elastic modulus of the elastic body 11 is 1 MPa or more.
