Abstract
Liquid developer is removed from support surfaces, such as reusable surfaces used for carrying latent electrostatic images, by blades with relative motion between the surface and the blades. Spreading of the liquid developer upon the cleaned portion of the surface during rest periods is prevented by reversing the relative motion between blade and surface and moving the blade away from the surface before each rest period.
Claims5
A method of cleaning liquid developer from an imaging surface which is capable of carrying an electrostatic latent image comprising intermittently moving the imaging surface in one direction relative to a stationary cleaning blade in engagement therewith with rest periods between periods of relative motion in said one direction, and before each such rest period reversing the relative motion between the stationary cleaning blade and the surface with the blade still in engagement with the surface and moving the cleaning blade away from said surface after reversing said relative motion.
Electrostatographic reproduction method comprising forming a latent electrostatic image on a moving support surface, developing the latent image with liquid developer, transferring the developed image to a support material and cleaning the liquid developer remaining on the support surface by intermittently moving said support surface in one direction relative to at least one stationary cleaning blade in engagement therewith with rest periods between periods of relative motion in said one direction, and before each such rest period reversing the relative motion between the stationary cleaning blade and the surface with the blade still in engagement with the surface and moving the cleaning blade away from the surface after reversing said relative motion.
