Zusammenfassung:A roller (11; Figs 1,2) for controlling the application of carrier liquid to an image bearing member (2; Figs 1,2) in an electrostatographic reproduction apparatus having a rigid porous electroconductive supportive core (46), a conformable microporous covering (47) provided around the core, and a pressure controller (48). The pressure controller (48) is located to provide a positive or negative pressure within the porous core (46) and across a cross section of the core (46) and covering (47).
