Abstract: A process for avoiding or minimizing comet formation which comprises dispersing in a magnetic toner comprised of resin particles, a first magnetite, carbon black, charge additive, and wax, a second soft magnetite; and wherein the toner contains a silica surface additive.

Abstract: A process for avoiding, reducing, or minimizing comet formation which comprises adding to the surface of a magnetic toner comprised of resin particles, magnetite, carbon black, optional charge additive, and wax, a surface additive mixture of silica, and magnetite.

Abstract: An apparatus which transfers a developed image from a photoconductive surface to a copy sheet. The apparatus includes a corona generating device arranged to charge the copy sheet. This establishes a transfer field that is effective to attract the developed image from the photoconductive surface to the copy sheet. A blade is moved from a nonoperative position spaced from the copy sheet, to an operative position, in contact therewith. The blade presses the copy sheet into contact with at least the developed image on the photoconductive surface to substantially eliminate any spaces between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet.
