Abstract
The invention provides a cleaning blade member having a controlled friction coefficient and a method for producing the same. The cleaning blade member, for use in a cleaning part for removing toner deposits, is formed of a polyurethane having a ratio of rebound resilience at 25° C. to Young's modulus (rebound resilience at 25° C./Young's modulus) of 4.5 or less.
Claims5
A cleaning blade member for use in a cleaning part for removing toner deposits, wherein the cleaning blade member is formed of a polyurethane having a ratio of rebound resilience at 25° C. to Young's modulus (rebound resilience at 25° C./Young's modulus) of 4.5 or less.
A method for producing a cleaning blade member for use in a cleaning part for removing toner deposits, wherein the method comprises blending a polyol, a polyisocyanate, and a cross-linking agent such that a polyurethane formed therefrom has a ratio of rebound resilience at 25° C. to Young's modulus (rebound resilience at 25° C./Young's modulus) of 4.5 or less.
