Abstract

A swing lever (55) swings around its base end stable roller (56) to move vertically its free end movable roller (57), so that the movable roller moves a conveyor belt (43) between a horizontal full color printing position and an inclined monochrome printing position. In the former position the belt contacts all of four colored image forming drums (41a, 41b, 41c, 42), and in the latter the belt keeps in contact with the black colored drum (42) by the stable roller. Further, a press roller (54) mechanically and electrostatically attach a sheet to be printed on the belt.
