摘要：
A cleaning blade of an image forming apparatus is formed of urethane rubber, a modulus of repulsion elasticity (JIS K6255) is not less than 20% at 10° C. to not more than 70% at 40° C., a 300% modulus (JIS K6251) is not less than 200 kgf/cm2, and a tear strength (JIS K6252 crescent type) is not less than 35 kgf/cm. A tension set (JIS K6262) of the cleaning blade (3) is preferably not more than 2.5%, and is more preferably not more than 1.0%, and is still more preferably not more than 0.5%.
