发明名称 Liquid development process with porous elastic development cleaning roller
摘要 An electrophotographic process involving the repeated cycles of a developing step for developing an electrostatic latent image formed on a latent image carrying member with a liquid developer, a transfer step for transferring the thus obtained visible image from said latent image carrying member onto another member, and a cleaning step for subsequently cleaning the surface of said latent image carrying member, comprising the use of an elastic rotary member composed of an electroconductive rigid core member, an electroconductive porous elastic member capable of retaining a liquid therein and provided around said core member, and a liquid-permeable insulating flexible member of a thickness in the range of 20 to 400 microns provided to surround the outer periphery of said elastic member, said elastic rotary member being maintained in pressure contact with said latent image carrying member, whereby said developing step is achieved by the liquid developer squeezed out from said elastic rotary member and the excessive liquid developer present on said latent image carrying member is recovered therefrom by absorption upon recovery of said elastic rotary member from the compressed state thereof.
