Abstract: A transfer surface of an intermediate transfer member in a printing apparatus is treated using an electrical discharge surface treatment. The treatment of the intermediate transfer member is to reduce negative dot gain from a previous image in subsequent printing or increase wettability of a silicone-based release layer.
