Amendment September 10, 1980 The title of the invention, the scope of claims for utility model registration, and the brief description of the drawings are amended as follows. ■Name of the invention Cleaning device for dry electrostatic printing equipment O Utility model registration Claim - A dry electrostatic developing device is used to convert an electrostatic latent image formed on a latent image drum having a photoconductive layer or a dielectric layer. A cleaning device for a dry electrostatic printing device that removes toner remaining on the latent image drum after developing it into a toner image and transferring the toner image to recording paper, the cleaning device cleaning the toner image on the surface of the latent image drum. It is composed of a brush made of thread that is provided in a contactable position and that can be charged to the opposite polarity to the residual toner, and a mesh electrode that gives the brush an electric charge of the opposite polarity to the residual toner by frictional charging with the brush. A cleaning device for a dry electrostatic printing device, characterized by: BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram for explaining the relationship between brush rotation speed and charging potential depending on the material of the brush, and FIG. 2 is a diagram for explaining an embodiment of a cleaning device for a dry electrostatic printing device according to the present invention. This is a diagram for In the figure, 4 is a cylindrical bristle brush, 5 is a mesh metal electrode,
6 is a metal case, and 7 is an electrostatic latent image drum.
