Liquid electrophotographic imaging system with a maximized solid toner ratio

摘要

A liquid electrophotographic developing apparatus capable of preventing image drift and reducing the load in the squeezing process. A developing roller faces a photoreceptor belt with a predetermined spacing to supply a liquid developer to the photoreceptor belt while rotating at a peripheral velocity in the opposite direction to that of the photoreceptor belt in a developing region thereon. A peripheral velocity ratio of the peripheral velocity to a moving velocity of the photoreceptor belt is determined so as to maximize a solid component ratio of a developed toner layer on the photoreceptor belt.
