Cartridge having molded resin electrode

摘要

A cartridge is provided with an electrode portion for connecting a main assembly contact. The cartridge electrode includes a first contact portion, exposed toward an outside of a frame of the cartridge, contacted to a main assembly contact provided in the apparatus main assembly. The cartridge electrode further includes a second contact portion provided for being electrically connected to a process means of the cartridge, and an injection receiving portion into which resin is injected when the cartridge electrode is molded into the frame. The electroconductive resin injected from the injection receiving portion is branched to mold the first contact portion and the second contact portion so that an electroconductive path for electrically connecting the main assembly contact and the process means is formed.
