ABSTRACT:
A toning shoe for applying fluid developer to a latent image on a supported sheet. A drum is the preferred support, with the toning shoe having raised upstream and downstream support rims contacting the sheet, opposed lateral insulating rims spaced very slightly from the sheet and a recessed electrode further spaced from the sheet. Fluid developer is injected through a slit into the shoe, flows as a thin film between the electrode and the sheet and then passes through a drain for collecting and recycling. The shoe moves laterally as the drum rotates so that development occurs in a helical stripe pattern.
