Abstract: In a configuration in which a metal holder is supported by a resin member, the metal holder cannot be grounded, so that electricity may be discharged from the charged holder to a substrate held by the holder. The holder is provided with a pin to determine a position of the holder with respect to a photosensitive member. A conductive member that is made of metal and is grounded, is brought into contact with the pin to thereby enable the holder to be grounded through the pin.
