<p>An ink pollution prevention device for use in a wet electrophotographic printer, for preventing a developer from polluting a photoreceptor and peripheral devices by flowing out at the ends of a development roller, a squeegee roller, or a cleaning roller. The ink pollution prevention device comprises a pair of ink stoppers (50,50') mounted around a shaft (13a) of each roller (13) in a symmetrical manner with each other. Each ink stopper (50,50') has a plurality of peaks (51) and recesses (52) which form a continuous helical shape in an opposite helical direction from the other ink stopper. The helical direction of the ink stopper (50,50') is formed to permit the ink in the ink stopper to flow toward the center of the roller (13) when the roller is rotated. <IMAGE></p> |
