    • An electrostatic color printer having a single toning shoe (17) for successively and sequentially applying color liquid developers to a color latent image overlay to a sheet (13) disposed against a rotating drum (11). An electrostatic head (15) scans the sheet in a helical pattern of abutting stripes (19) and forms the latent image on the sheet. A toning shoe assembly (53) follows the head and applies one of the color developers to the sheet. A drain selector foot (18), pivotable beneath the toning shoe, brings an appropriate developer recycling tube (20) into communication with a drain in the toning shoe assembly. After scanning the sheet, the toning shoe is rinsed with a solvent at a cleaning station (26) past the end of the drum.
