Abstract

1,272,676. Transferring electrostatic images. EASTMAN KODAK CO. July 1, 1969 [July 1, 1968], No.33229/69. Heading G2H. [Also in Division B6] An apparatus for transferring a developed electrostatic image from one or more images bearing members 22 on to a receiver 21 hasatransfer roller 10 for supporting the receiver. The transfer roller 10 has teeth 24 and (25) Fig. 4 (not shown) which engage registration notches 26 and (27) Fig. 4 (not shown). The sides of the notches engage the teeth to produce correct registration of the receiver 21 and image bearing members 22. An electromagnet 32 is energized, upon closure of a micro-switch 33, to hold the adjacent member 22 in fixed position during image transfer. The transfer step is repeated for each member 22 to produce a composite image, e.g., a colour image, during movement of a belt 12 carrying the roller 10.
