Squeegee roller liquid electrophotographic printer
摘要:
A squeegee roller for a liquid electrophotographic printer includes a steel core and an elastic rubber layer coated on an outer circumferential surface of the steel core. The elastic rubber layer forms a squeegee nip by contacting a photoreceptor web, thereby to make a toner of the excess developer, which is developed in an area for an electrostatic latent image of the photoreceptor web, into a thin film in the area for electrostatic latent image and to squeeze the remaining carrier. The roughness (Ra) of a surface of the elastic rubber layer satisfies the condition, 1.5 &mgr;m≦Ra≦2.5 &mgr;m. Further ,a criss-cross grove pattern is formed on the surface of the squeegee roller so as to guide the excess developer liquid
