Liquid electrophotographic printing apparatus having structure so that differences in peeling forces can be controlled

A liquid electrophotographic printing apparatus including:

• a photosensitive belt circulating around a predetermined track, the photosensitive belt having a toner image thereon;
• a transfer roller contacting the photosensitive belt, such that the toner image transfers from the photosensitive belt to the transfer roller;
• a fuser roller pressing against the transfer roller with a pressing force, such that the toner image transferred to the transfer roller is transferred to a sheet passing between the transfer roller and the fuser roller;
• a fuser roller cleaning device selectively contacting the fuser roller and maintaining a peeling force of the fuser roller within a predetermined range;
• and
• a peeling force adjusting device selectively contacting the transfer roller and maintaining a peeling force of the transfer roller within a predetermined range,
• wherein surface energies SET, SEP, and SEF of the transfer roller, the sheet, and the fuser roller, respectively, satisfy the following inequality
• SET<SEP<SEF.
