Developing roller and imaging apparatus comprising the same |
摘要 |
There is a developing roller having a low compression permanent strain without contaminating a photosensitive drum and deteriorating toners. The developing roller 1 comprises a shaft 2, an elastic layer 3 formed on an outer periphery of the shaft 2 and a surface coating layer 4 formed on an outer peripheral face of the elastic layer 3, in which the surface coating layer 4 comprises a urethane resin formed by crosslinking a lactone-modified polyol with a polyisocyanate. The urethane resin is preferable to be formed by crosslinking the lactone-modified polyol with two or more kinds of polyisocyanates.
