The invention provides a
chip module, a developing box, a
processing box and an electrophotographic imaging device, the
chip module comprises a mounting base, a forced pushing block and a
chip assembly, the mounting base is provided with a guide groove, the forced pushing block is slidably mounted in the guide groove, the guide groove penetrates through the mounting base in the forced pushing direction of the forced pushing block, the chip
assembly comprises a substrate and a contact elastic sheet group, and the contact elastic sheet group is arranged on the substrate. The base plate is installed on the installation seat, the contact elastic piece set is installed on the base plate and electrically connected with the base plate, a part of the contact elastic piece set is located at the downstream end of the guide groove in the forced pushing direction, and when the forced pushing block is pushed to move in the forced pushing direction, the forced pushing block can push the contact elastic piece set to elastically deform back to the guide groove. And enabling the contact elastic sheet group to be in contact with a contact
pin group in the electrophotographic
imaging equipment. A
processing box is arranged in the electrophotographic
imaging equipment, the
processing box comprises a developing box, the developing box is provided with the chip module, and the chip module can ensure that the chip
assembly is stably and electrically connected with an
electric contact pin in the electrophotographic
imaging equipment and does not hinder the installation of the developing box.
