Apparatus for removing toner after a selected time interval from a longitudinal member in a dry electrophotographic printer for printing a visible image on a receiver. An end block is disposed at one end of a rotatable development member, and a longitudinal member is disposed adjacent to the development member or photoreceptor and is connected to the end block. A backup bar is disposed adjacent to the photoreceptor and can selectively make physical contact with at least one point on the end block. When a measured time interval of printer operation reaches the selected time interval, a controller causes the backup bar to apply a selected force to the end block to cause toner on the longitudinal member to be removed from the member.
