摘要： An image printing apparatus includes a photoreceptor belt on which a latent electrostatic image is formed, and a plurality of development devices for developing the latent electrostatic image formed on the photoreceptor belt. Each of the development devices has a development roller for coating a developer liquid on the photoreceptor belt, and a squeegee roller for removing excess developer liquid from the photoreceptor belt. A roller driving means drives the squeegee rollers, and an elevating means elevates the development devices. The plurality of development devices are supported by a pair of frames that are spaced apart a predetermined distance from each other. The roller driving means commonly drives the squeegee rollers of the development devices. The frame elevating means displaces the pair of frames, such that the squeegee rollers are simultaneously in contact with or out of contact with the photoreceptor belt.

摘要： In a squeeze roller assembly of a wet type developer of an electrophotographic printer, a shaft is rotatably installed in a frame. A first roller is fixed on the shaft for filming solid toner from a developing liquid onto a photosensitive belt. Second rollers are rotatably installed on the same shaft at both sides of the first roller. The first roller, attached to the central portion of the imaging surface of a photosensitive belt, rotates in the same direction as that of the conveying direction of the photosensitive belt. The second roller rotates in a direction opposite to the direction of the photosensitive belt by an inverse rotator. Therefore, it is possible to reduce the required installation space by having the first and second rollers share a common shaft as a rotating axis.

摘要： 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.
