In electrostatographic machines where reflex exposure and dipole development is contemplated, a web or belt type photoconductor can be employed. The original document is brought into contact with and exposed through the photoconductor. This gives rise to problems because foreign objects such as dust, staples, paper clips and the like can engage the photoconductor thereby causing scratches and imperfections therein. Further, pressure transfer may leave undesirable quantities of toner on the photoconductor. The imaging member, after double-sided charging by corona, for example, or the like, is brought to the reflex exposure station. Here the original document is brought into contact with the insulating base side. The photoconductor cannot be harmed by any staples, dust, etc., between the original and film's base side. This makes recycling of such a structure more appealing. After exposure, development can be accomplished on the insulating base side. Should development be necessary in a non-light tight region, an optional recharge-flood exposure step can be used.
