摘要： A photosensitive member to be used for an image-forming apparatus can effectively suppress its wettability of the surface relative to foreign objects adhering to it and reduce the load and the mechanism necessary for cleaning the surface so as to prolong the service life of the photosensitive member and make the apparatus adapted to down-sizing. For this purpose, the wettability (W: work of adhesion) of the surface of the photosensitive member relative to toner is confined to be between 60 and 110 mN/m.
