Abstract
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.
