Abstract
An image fusing unit of a liquid electrophotographic unit for fusing an image developed by a developer which is a mixture of toner particles and liquid solvent and transferred onto a sheet of paper includes a charging portion installed on a transfer path of the paper for applying electric potential in a direction in which the toner is in close contact with the paper, a drying portion for drying the image by directly contacting and heating the paper, and a fusing portion for fixing the image to the paper by heating and pressing the paper. Thus, the efficiency of heat can be improved by drying in the direct contact method. Also, by closely pressing the toner against the paper prior to drying, the disadvantage according to the contact type drying method, that is, the toner adheres to a contact member, can be solved.
