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, said first and second donor members both being arranged to receive toner particles from said 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 means for moving the outer surface of first donor member at a first velocity; means for moving the outer surface of second donor member at a second velocity; wherein said first velocity is different than said second velocity to reduce a ghosting print defect, said first donor member develops a first ghost image on said imaging surface and said second donor member develops a second ghost image on said imaging surface that overlays said first ghost image by a predefined separation gap.
