ABSTRACT:
A novel apparatus and method for pressure fixing imaging powder to a receptor (such as paper) to produce photocopies having reduced gloss is provided. The apparatus comprises non-compliant pressure members (e.g., pressure rollers) one of which has a surface of defined texture or roughness. An offset prevention material is applied to the textured pressure member such that offset of imaging powder from a receptor passing between the pressure members to the textured pressure member is essentially prevented.
