摘要： A developing roller employed in a developer in which toner carried on the surface of the roller which is or not brought into contact with a photosensitive element is supplied at least onto the photosensitive element, and which is incorporated in an apparatus of electrophotography type such as a printer, a copier, or a facsimile machine. A conductive elastic layer is provided around a conuctive shaft and the outer circumference is covered with a surface layer which is made of resin composition whose contact angle is more than 35 DEG when measured using a liquid whose main component is similar to the resin component of the toner as a dripped liquid. Filming does not occur, the initial image density is good and the toner crackings are reduced.
