摘要： A developing roller having a rubber elastomer layer on the outer periphery of a shaft core metal, having a coating layer formed from a binder (A) and silicone rubber particles (B) on the surface of the rubber elastomer, and having an electrostatic capacitance of 4 to 20 nF; wherein the binder (A) is formed from a diluting solvent solution of a terminal hydroxyl group-containing prepolymer (a) obtained by reaction of an isocyanate compound, an isocyanurate modified product thereof and a reactive silicone oil, and an isocyanate compound and/or an isocyanurate modified product thereof (b). This developing roller suppresses banding by suppressing electrostatic capacitance even if the nip width between the developing roll and the photoreceptor changes due to distortion of peripheral members in the development apparatus, and stick slip (vibration) of gears.

摘要： Disclosed is a cleaning blade, having an elastic body formed of a rubber base material molded product, and a surface treatment layer on at least an area of the elastic body to be brought into contact with a cleaning object. The surface treatment layer is formed by impregnating a surface portion of the elastic body with a surface treatment liquid containing an isocyanate compound and an organic solvent, and hardening the liquid. The surface treatment layer has an indentation elastic modulus of 21 MPa to 56 MPa. The elastic body has an indentation elastic modulus greater than 20 MPa and 35 MPa or less. The difference in indentation elastic modulus between the surface treatment layer and the elastic body is 1 MPa to 21 MPa.
