Abstract
A cleaning blade member for use in a cleaning section for removing toner on a toner-deposited body, the cleaning blade member comprising: an edge layer contacting the toner-deposited body; and a back layer provided on a back side of the edge layer, and wherein the edge layer has a Young's modulus of 8 to 20 MPa and an impact resilience at 25° C. of 20 to 40%, and when the Young's modulus of the edge layer is designated as E, a Young's modulus of the back layer is designated as E, a thickness of the edge layer is designated as T, and a thickness of the back layer is designated as T, a ratio (R/R) between a contribution rate Rof the Young's modulus of the edge layer represented by the following equation (1), and a contribution rate Rof the Young's modulus of the back layer represented by the following equation (2) is 0.01 to 6.0, and a total Young's modulus (R+R) of the edge layer and the back layer is 7 to 14 MPa:/()]  (1)/()].  (2)
