Abstract
In an electrophotographic method using a screen-like photosensitive medium having a number of fine openings to effect image formation, an air stream directed toward corona discharge means is maintained in the openings of the screen-like photosensitive medium when the corona discharge means, at least during the process of latent image formation, is in operation.
