Abstract
This specification discloses a method of making the grid of a corona discharger device and a method of mounting the corona discharger device on an apparatus body, and more particularly a method of easily forming a number of grids and a method of mounting a corona discharger device having such grids on an apparatus body. The grid making method of the present invention comprises winding an electrically conductive thin wire on a rotatable body, fixing the wound thin wire in the direction of the rotational axis of the rotatable body, fixing the wound thin wire in the direction of the rotational axis of the rotatable body by means of fixing members, and cutting the thin wire in the direction of the rotational axis. The method of mounting a corona discharger having a number of grids with respect to an apparatus body enables the grids to be highly accurately mounted with respect to the surface of an electrically charged member by using the surface of a grid supporting member which faces the charged member as the standard surface for determining the distance between the surface of the charged member and the surface of the grid supporting member.
