<P>PROBLEM TO BE SOLVED: To provide a cleaning blade for an electrophotographic apparatus, which is hardly broken during molding and in which the occurrence of defects in an edge caused by the friction with a photoreceptor is almost suppressed. <P>SOLUTION: The cleaning blade for the electrophotographic apparatus has an elastic blade member formed from a polyurethane elastomer. The polyurethane elastomer contains at least following components (A) to (D); (A): a polyisocyanate, (B): a polyester polyol having an acid value of ≤2.00 mgKOH/g, (C): a chain extender formed from a polyol having a molecular weight of ≤200, and (D): a catalyst for curing polyurethane. <P>COPYRIGHT: (C)2010,JPO&INPIT |
