Abstract

1,252,917. Developing electrostatic images. RANK XEROX Ltd. (Fuji-Xerox CO. Ltd. Nov.22, 1968, No. 55543/68. Heading G2H. A web 6 carrying a latent electrostatic image is developed in a container 1 filled with an insulating carrier liquid and charged toner. The web passes through a toner free zone 3 created by electrodes 4, 5 before development, such that the web is wetted with carrier liquid, thereby impregnating fine irregularities in both surfaces of the web. Thus, toner particles are prevented during development from being trapped in the irregularities and background density is reduced. The toner free zone is created by electro-phoresis, whereby charged toner particles are attracted towards one electrode 4 or 5.
