Abstract

1,173,377. Developing electrostatic images. FUJI SHASHIN FILM K.K. Nov.8, 1967 [Nov. 9, 1966], No.50770/67. Heading G2H. Photo-conductive toner 8 is removed from non-image areas of a base 5 by a current of air from an outlet 1 directed downwardly. The toner particles so removed are guided by a plate 2 resting lightly on the base 5 and withdrawn by vacuum. Reference has been directed by the Comptroller to Specification 1, 059, 649.
