Abstract
A cleaning blade includes a contact part coming into contact with a member to be cleaned, the contact part being constituted by a member containing polyurethane rubber produced by polymerizing at least a polyol component and a polyisocyanate component. The ratio (M100/Re) of 100% modulus (M100 [MPa]) to rebound resilience coefficient (Re [%]) of the member is 0.25 or more. The rebound resilience coefficient (Re [%]) of the member is less than 25%. The tensile stress at 23° C. and 200% strain of the member is 15 MPa or more.
