Liquid electrophotographic printer using electrostatic transfer

Provided is a liquid type electrophotographic printer using an electrostatic transfer method. The printer includes a photosensitive belt (110) having a charging surface (193) and a back surface (194) and rotating along a printing path, at least one exposure unit (140a) for selectively discharging the charging surface (193) of the photosensitive belt (110) in order to form an electrostatic latent image, at least one developing unit (150a) for developing the electrostatic latent image on the photosensitive belt (110) into toner image using an ink including a liquid carrier and charged toner particles, and including a developing roller (151a), a toner removing roller (152a), a squeeze roller (153a), and backup rollers (251a,252a,253a) corresponding to the developing roller (151a), the toner removing roller (152a), and the squeeze roller (153a) at the back surface (194) of the photosensitive belt (110), wherein the photosensitive belt (110) is arranged around the at least one of the backup rollers (251a,252a,253a) with a wrap angle of 1 DEG contact wrap, and an electrostatic transferring unit for transferring the toner image formed on the developing unit (150a) to a printing medium from the photosensitive belt (110) using an electrostatic force.
