Liquid developing apparatus for use in electrophotographic copying machine |
摘要 |
Apparatus for an electrostatic copying machine using a liquid developer or toner includes a pair of electrodes for developing the latent image on the electrostatically charged photosensitive sheet, of which the auxiliary or back electrode has a specially grooved surface such that the contact area with the sheet is smaller at the front and rear ends of the auxiliary electrode than at the central portion. In one embodiment, the grooves comprise two series of uniformly spaced identical circular arcs, the two series having opposite curvatures for intersection and defining the contact areas.
