Abstract

Abstract A recording apparatus according to the present invention in which a data is recorded by charging a recording medium, scanning laser beams on the recording medium to form electrostatic latent images thereon, and developing and transferring the electrostatic latent image, comprises a charger for charging the recording medium; and at least two image forming device disposed around the recording medium for recording multi-colored and/or uni-colored data in a plurality of print modes. In the recording apparatus, the print modes is controlled so as to drive the second image forming device corresponding to the second print mode after the operation of the first print mode is closed, when the second print mode is designated in the operation of the first image forming means corresponding to the first print mode. And, the driver for driving the recording medium is controlled so as to continuously drive the recording medium when the first print mode is switched to the second print mode by the switching device. The image forming device comprises device for forming an electrostatic latent image on the recording medium by scanning laser beams in accordance with the recording data and device for developing the electrostatic latent image.
