<P>PROBLEM TO BE SOLVED: To provide a cartridge having an electric contact part made of a conductive resin, in which electric resistance of the conductive resin is further reduced. <P>SOLUTION: A cartridge comprises a contact part which is formed by injecting a conductive resin into a space between a mold 27 contacting a drum cartridge frame body 13 and the drum cartridge frame body 13 and becomes a conductive path between an apparatus body and a charging roller when the cartridge is attached to the apparatus body. The contact part includes a resin projection 19g projecting from a surface of the drum cartridge frame body 13, the resin projection 19g having a shape formed by changing a flow direction of the conductive resin injected into the space by a rib 13k provided in the mold 27 or the drum cartridge frame body 13, when the contact part is formed in the drum cartridge frame body 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
