Abstract

Printing or photocopying apparatus for forming a toner image on a receptor sheet (35) comprises a imaging roller (25); means (19, 31) for forming a toner image on the imaging roller; and a transfer roller (37) in rolling contact under pressure with the imaging roller, the transfer and imaging rollers being maintained in non-parallel orientation with the receptor sheet fed therebetween to receive the toner image.
