Abstract
Abstract An electrostatic reproduction machine has a photoconductive member and a transfer roller in contact therewith, the roller having a texturized surface formed so as to prevent or minimize the possibility of a sheet of paper wrapping itself around the roller as the sheet is passing between the photoconductive member and the roller during the transfer operation.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
118 words
A reproduction machine comprising: means defining a surface, the surface being mounted for movement around a closed path; means for forming a developed electrostatic image on the surface; a transfer roller in contact with the surface and mounted for rotation about an axis; means for feeding a sheet of support material between the surface and the transfer roller so that transfer of the developed electrostatic image from the surface to the sheet can be effected as the sheet is moving therebetween; and means formed on the peripheral surface of the transfer roller for preventing the sheet from electrostatically tacking itself to the transfer roller during transfer while simultaneously causing the sheet to electrostatically tack itself to the surface.
