Abstract
A stencil printer of the present invention includes a print drum and a pressing member. After a cut stencil or master has been wrapped around the print drum, the pressing member presses a paper or similar recording medium against the master. As a result, ink fed to the print drum oozes out to the paper and prints a desired image thereon. When the pressing member presses the paper against the master, an electric field is formed between the pressing member and the print drum in the direction in which the ink migrates from the drum to the paper. The printer is capable of adjusting image density without varying a mechanical pressure to act on the drum or varying the print speed.
