Abstract
A liquid electrophotographic reproduction machine for producing a toner image reproduction on a copy sheet. The reproduction machine includes an image bearing member movable along a process path, latent image forming devices mounted along the process path for forming a latent image electrostatically on the image bearing member, and a development unit. The development unit is mounted along the process path and contains liquid developer material including a liquid carrier and charged dispersed toner particles for developing the latent image to form a toner image. The reproduction machine also includes a transfix assembly mounted along the process path for transferring and simultaneously heating and fixing the toner image onto a copy sheet. In order to increase the abrasion fix level of produced toner image copies, the reproduction machine further includes a separate fusing apparatus mounted downstream of the transfix assembly relative to copy sheet movement for selectively and additionally heating and pressurizing the transfixed image onto the copy sheet.
