Abstract
An apparatus in which a developer roller transports developer material into contact with a photoconductive surface having either a continuous tone or a half-tone latent image recorded thereon. The speed of the developer roller is controlled so that it rotates at a higher speed when developing the continuous tone latent image than when developing the half-tone latent image. In this way, development is optimized for the continuous tone and half-tone latent images so as to produce high quality copies.
