Cleaning blade and electrophotographic apparatus

摘要

In a process for producing a cleaning blade, a blade formed of a urethane resin is impregnated with an isocyanate compound at its surface portion. Thereafter, warm air or hot air is blown on the blade surface to remove the isocyanate compound remaining thereon, and then the urethane resin that forms the blade is allowed to react with the isocyanate compound with which the blade stands impregnated, to form a cured layer.
