Abstract
A toning shoe for applying fluid developer to a latent image on a supported sheet. A drum is a preferred support, with a toning shoe having raised edges, a central recessed area contacting the sheet and a drain. Fluid developer is injected into the shoe under pressure from an opening and flows to the drain, contacting the sheet between the opening and the drain, and then is collected and recycled back to the shoe. The shoe is moved laterally as the drum rotates so that development occurs in a stripe pattern.
