Abstract
A cleaning blade includes a contact part coming into contact with a member to be cleaned, the contact part being configurated by a member containing polyurethane rubber produced by polymerizing at least a polyol component, which contains over 50 mol % and 75 mol % or less of 1,4-butanediol relative to the entire polyol components, with a polyisocyanate component. The ratio (M100/Re) of 100% modulus (M100 [MPa]) to rebound resilience coefficient (Re [%]) is 0.25 or more. The rebound resilience coefficient (Re [%]) is 25% or more.
