Abstract
An apparatus in which at least a pair of developer rollers deposit toner particles on an electrostatic latent image recorded on a photoconductive member to render it visible. One of the rollers rotates at a first tangential velocity being spaced a first distance from the photoconductive member. The other roller rotates at a second tangential velocity being spaced a second distance from the photoconductive member. The second tangential velocity is greater than the first tangential velocity with the second distance being less than the first distance.
