Abstract

1334883 Liquid developing apparatus FUJI PHOTO FILM CO Ltd 24 Nov 1971 [25 Nov 1970] 54643/71 Heading G2H A sheet bearing an electrostatic latent image is transported along a path by pairs of rollers and sprayed with developer liquid via the rollers; the rollers which face the imaged surface being predominantly insulating over a first part of the path so that development initially takes place with little or no development electrode effect and being predominantly conductive over the rest of the path so that development is continued under the influence of development electrodes it is stated that this produces uniform, streak-free development. As shown, rollers 31-1, 31-2 are insulating or metal coated with insulator and all the other rollers are conductive. To produce a gradual transition from insulating to conductive the initial rollers may bear insulating coatings which decrease in thickness or resistivity in the direction of sheet transport. Alternatively, the roller-image spacing may decrease.
