Abstract

In a liquid development xerographic apparatus, image quality may be improved by the addition of an extra treatment station 1 following the cleaning station 2. The extra station in-eludes an applicator 3 for applying to the imaging surface a cleaning liquid of lower electrical conductivity than the developer liquid and a device 4 following this applicator for substantially removing liquid from the surface, This arrangeS-ment reduces lateral charge conduction on the imaging surface between the exposure and development operations (as compared with when the extra station is not used) , thereby improving image quality. The applicator is typically an applicator roller, and the device for substantially removing liquid is typically a blade-cleaning device.
