Abstract
An apparatus for developing a latent image recorded on a movable imaging surface, including: a reservoir for storing a supply of developer material; a first donor member and a second donor member, the first and second donor members both being arranged to receive toner particles from the reservoir and to deliver toner particles to the image surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; and system for moving the outer surface of first donor member at a first velocity; and system for moving the outer surface of second donor member at a second velocity; wherein the first velocity could be slightly different than the second velocity to reduce a ghosting print defect.
