CLEANING BLADE FOR ELECTROPHOTOGRAPHIC DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

This invention provides a cleaning blade for an electrophotographic device, which, even when a spherical (truly spherical or irregularly shaped) and small-particle diameter toner produced by polymerization is used, can simultaneously realize abrasion resistance and cleaning properties (particularly cleaning properties under low-temperature and low-humidity conditions). The cleaning blade for an electrophotographic device comprises an elastic rubber member and a support member. The elastic rubber member has a two-layer structure comprising an edge layer and a base layer. The edge layer is formed of a material having a JIS A hardness of 65 to 72° and an impact resilience of 10 to 35%, as measured at 23ºC. The base layer is formed of a material having a JIS A hardness of 70 to 80°, which is larger than the edge layer, and an impact resilience of 40 to 70%, as measured at 23ºC.
