Abstract:
1. A cleaning blade to remove a residual toner present on a surface of an electrophotographic photoreceptor, wherein a value of the shear modulus of the cleaning blade over the change in a temperature range of about −5° C. to about 23° C. and a value of the shear modulus of the cleaning blade at a temperature of −5° C. obtained from a dynamic viscoelasticity measurement measured as a function of temperature in a temperature range of about −80° C. to about 50° C. under conditions of a frequency of 10 Hz, a heating rate of 2.0° C./min, and an initial strain rate of 0.03% satisfy the following conditions: wherein ΔG*(MPa)/ΔT(° C.) is a rate of the change in the shear modulus value G* (unit: MPa) over the change in a temperature range ΔT(° C.) of about −5° C. to about 23° C., and G*(MPa)@−5° C. (unit: MPa) is the shear modulus value at the temperature of −5° C.
