Patent ID: 8494416

Claim:
An image forming apparatus comprising: a first development unit performing a development with a first developer absorbing a light having a prescribed wavelength; a plurality of second development units performing the development with second developers having a different color respectively, permeating the light having prescribed wavelength therethrough; a communication unit receiving print data including background design image data and print image data; a control unit controlling print of the background design image data by the first development unit and print of the print image by the second development units; an analyzing unit determining whether or not the received print data includes the background design image data; and an image data conversion unit converting a portion of the print image data to be printed with the first developer into the portion of the print image data to be printed with a combination of the second developers in a case where the print data includes the background design image data according to a determination result at the analyzing unit, wherein, in a case where the print data includes the background design image data, the control unit controls to form an image of the background design image data by the first development unit, and to form an image of the print image data by the second development units, and wherein, in a case where the print data does not include the background design image data, the control unit controls to form the image of the print image data by both of the first development unit and the second development units.
