Abstract

844,457. Electrophotographic development. RADIO CORPORATION OF AMERICA. July 22, 1957 [July 31, 1956], No. 23193/57. Drawings to Specification. Class 98(2) [Also in Group XXXVI] In a method of electrostatic printing in which the recording element consists of semi-conductive layers (see Group XXXVI), the developer powder may consist, of powdered zinc or powdered copper. The carrier material for magnetic brush development may consist of "alcoholized" iron particles ranging in size from 0À001 to 0À020 inch, preferably 0À002 to 0À008 inch.
