<p>A charging member contactable to a member to be charged to electrically charge it, the improvement residing in that a microhardness of an end region, with respect to a longitudinal direction, of the charging member is larger than that in a central region of the charging member. This increase can be obtained by increasing the coating layer, changing the vulcanization condition, or using a solid ma terial for the end region.</p> |
