摘要： A development apparatus for a liquid electrophotographic printer includes a development roller for supplying a developer liquid to a photoreceptor belt on which a latent electrostatic image is formed, a plurality of squeegee rollers for removing excess developer liquid sticking to the photoreceptor belt, at least one cleaning device having a rotary body rotatably installed in proximity with at least one of the plurality of squeegee rollers, and a plurality of blades installed on the perimeter of the rotary body at a predetermined spacing, in contact with the surfaces of the respective squeegee rollers, and a rotation mechanism for selectively bringing one of the plurality of blades into contact with the surface of each squeegee roller. Therefore, when one blade is worn, the worn blade can be replaced with a new one without dismantling the development apparatus, and thus the life of the development apparatus is prolonged.

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.
