Abstract

PURPOSE:To accurately index a switching position by setting the switching timing for switching and driving plural developing devices selectively with digital data sent out of a host device. CONSTITUTION:The switching timing for switching and driving the plural developing devices 4 and 5 using developers of different colors selectively is set with the digital data sent out of the host device 71. The switching between the developing devices 4 and 5 in the printer is performed in one page to be printed to easily realize simultaneous multicolor printing. Consequently, the switching position is accurately indexed with high resolution. Further, when the digital data on the switching position is based upon the distance from the front end of a form, the data matches with sensational specification by an operator of the host device 71 and when the data is based upon a line number, the data is specially effective in handling a character image; when the data is based upon a raster number, this is specially effective in handling a graphic image.
