Abstract
In an electrophotographic reproduction device, such as a copier or a printer, having a transfer station (17) whereat toner images are sequentially transferred from the surface of a moving photoconductor (10) to the adjacent surface of sheets of moving and spaced transfer material, such as paper, the transfer station is controlled in a manner to produce a substantially similar electrical effect on the photoconductor both when a sheet of transfer material resides in the transfer station intermediate the photoconductor and the transfer station, and when no sheet of transfer material is intermediate the photoconductor and the transfer station.
