Abstract
Provided is a cleaning blade having an elastic body that is a molding of a rubber substrate and having at least a surface-treatment layer at a position that contacts a contact-receiving site on the elastic body. The surface-treatment layer contains a cured product from an isocyanate group reaction product of a difunctional isocyanate compound with a difunctional polyol and a trifunctional polyol wherein the molar ratio of the difunctional polyol to the trifunctional polyol (difunctional/trifunctional) is 50/50 to 95/5. The cured product reacts via the isocyanate group with the polymer forming the elastic body, and the surface-treatment layer has a thickness of at least 10 μm and not more than 100 μm.
