LIQUID DEVELOPING METHOD OF ELECTROSTATIC LATENT IMAGE AND LIQUID DEVELOPING APPARATUS

摘要

This invention relates to a liquid developing method of an electrostatic latent image and a liquid developing apparatus which can prevent distortion of an image due to adhesion of toner to a non-image portion of an image supporter. The developing method includes the step of applying a pre-wet solution to a photosensitive member (10), and the development step of forming a thin layer of a liquid developer having a high viscosity and prepared by dispersing toner with a high concentration in an insulating liquid, on a developing roller (506) having flexibility, and bringing the liquid developer layer on the developing roller (506) into contact with the pre-wet liquid layer on the photosensitive member (10) while rotating the developing roller (506) so as to supply the liquid developer to the latent image surface of the photosensitive member (10), thereby developing the electrostatic latent image formed on the photosensitive layer (10) by the toner.
