ABSTRACT:
A liquid electrophotographic image-forming apparatus is provided including an anti-wraparound device having a bushing formed on both ends of a rotary shaft of a transfer backup roller to slide thereon, a shielding member installed on the bushing and contacting the transfer belt and the cleaning blade to prevent developer removed by the cleaning blade from flowing to the sides of the transfer belt, and an elastic member installed on both sides of the transfer backup roller for elastically biasing the bushing toward the transfer belt. Therefore, a wraparound phenomenon generated on the sides of the cleaning blade and transfer belt can be prevented, thus obtaining a higher image quality.
