DEVELOPER LIQUID SUPPLYING DEVICE ABSTRACT OF THE DISCLOSURE A resilient, patterned liquid developer applicator having raised and depressed areas for applying liquid developer to latent electrostatic images, is doctored by contacting it first with a squeegee roller to meter the depressed areas and subsequently with a relatively rigid raised area cleaning blade. The applicator has a resilient surface with a hardness of more than 60 Shore A and is provided with a plural number of finely divided discrete depressions and raised portions, and the squeegee doctor roller has a non-absorbing surface which has a hardness generally greater than the hardness of the surface of the applicator so that developer is squeezed from the depressions when the raised areas are deformed by the action of the squeegee roller.
