Abstract
A process of forming a composite toner image, for example, a two color image, includes steps of charging and exposing an image member to create a first electrostatic image and developing the image to form a first toner image. The process is repeated to form two toner images on the same area or frame of an image member. To reduce the tendency of the first toner image to spread into the second electrostatic image and also to reduce scavenging of the first toner image by the second toning step, the image member is exposed, immediately after the formation of the first toner image, to uniform activating radiation to form charges of a polarity opposite the electrostatic image, which charges tend to hold the first toner image to the image member. The uniform exposure can be effected through a transparent support to the image member.
