Abstract
A design method of transfer condition for electrophotographic printing on a booklet has been developed. There are three main problems in developing a printing system for a electrophotographic booklet printer; the design of the transfer potential for printing, consideration of effect of transfer pressure and dirtiness of pages. Whereas the conventional method can calculate the electric charge for printing on single paper, our new method was found experimentally to be able to calculate a necessary and sufficient voltage for electrophotographic printing on a booklet. And transfer pressure was found to be related to transfer potential. Since the main material that disturbs electrophotographic printing was found to be oleic acid, a cleaning roller made of butadiene rubber with oil-absorbing resin was developed.
