Abstract

An apparatus in which a plurality of developer rollers develop a latent image recorded on a flexible photoconductive member. The photoconductive belt is deflected by the developer material to wrap around at least a portion of the first two developer rollers forming wrapped development zones. The last developer roller may either have the photoconductive belt wrapped about a portion thereof, or the photoconductive belt may remain in an undeflected condition. The developer rollers having the photoconductive belt wrapped thereabout rotate in opposite directions. A blanket of developer material is formed between the last two developer rollers. An apparatus of this type optimizes development of the latent image recorded on the photoconductive member.
