する電子写真装置。[Scope of Claim for Utility Model Registration] A metal case with a corona discharge wire insulated and supported inside, and locking protrusions provided at multiple locations on both longitudinal ends of an opening at one end of the metal case. A charging device comprising a grid electrode plate fitted into a locked protrusion insertion hole provided in the longitudinal direction of the grid electrode plate corresponding to the installation position of the protrusion and coupled to the opening surface of the metal case; In an electrophotographic apparatus equipped with static elimination lamps arranged adjacent to each other, the grid electrode plate has an inverted L-shaped cross section and is provided with a light shielding plate portion having approximately the same length as the metal case, and a static elimination lamp mounting plate portion provided approximately at right angles thereto. The presser foot and light shielding plate,
The light-shielding plate portion allows the tip of the light-shielding plate portion to be brought close to the surface of the photoreceptor and fixed to one longitudinal side of the metal case of the charging device, and also to fix the surface of the light-shielding plate portion to the metal case. The entire length is integrally provided with a grid electrode plate holding protrusion that presses one longitudinal end of the grid electrode plate against one longitudinal side end of the metal case at right angles to the fixing surface. An electrophotographic apparatus characterized in that a conductive tape is pasted across the metal case and the grid electrode plate at the side end opposite to the side edge pressed by the protrusion to fix the grid electrode plate to the metal case.
