Title: Squeezing apparatus of a liquid electrophotographic printer

Abstract: A squeezing apparatus of a liquid electrophotographic printer includes a squeezing roller for squeezing out and removing the carrier from a developer which is applied on a photosensitive belt by its passive-rotational movement while being pressed into tight contact with the photosensitive belt at a certain pressure together with a squeezing backup roller, a squeezing brush selectively coming in contact with the outer circumference of the squeezing roller, for cleaning the squeezing roller by being rotated by a separate driving section, and a squeezing roller slip prevention mechanism disposed on both ends of a shaft of the squeezing roller to come in tight contact with the squeezing backup roller during the pressing of the squeezing roller, for preventing any occurrence of slip of the squeezing roller with respect to the photosensitive belt. The squeezing roller slip prevention mechanism includes a friction roll in friction contact with the squeezing backup roller, a bush bearing for supporting the friction roll with respect to the shaft of the squeezing roller, and an one-way bearing disposed between the bush bearing and the squeezing roller, for permitting free backward-rotation of the squeezing roller with respect to the friction roll in the drip line removing mode.
