Abstract
A rubber member for coating a developing roll which is obtained by coating a coating layer component around a developing roll having a rubber substrate layer and curing the coating layer component is described. The coating layer component contains: (A) a liquid binder containing at least a polyol, an isocyanate compound and reactive silicone oil; (B) silicone rubber particles having a hardness according to JIS K6253: 1997 by Durometer A, measured instantaneously, of 20 to 80 degrees, and a rubber particle size of 0.2 to 10 pm; and a diluting solvent. A ratio of a thickness of the coating layer after curing and a particle size of the rubber satisfies: the rubber particle size/a coating layer thickness <0.3.
