摘要： There is provided an image forming apparatus for performing printing in a plurality of colors. The image forming apparatus includes processing circuitry. The processing circuitry is configured to receive first print data in which an object to be printed in a spot color is designated in a first area in a document to be printed and second print data of the document to be printed from an information processing apparatus; convert the second print data received by the communication unit into image data of a predetermined color; extract an image of the first area from the image data obtained by conversion of the drawing unit; convert the image of the first area extracted by the spot color image control unit into the spot color; and generate image data of the spot color in which the image of the first area converted by the conversion unit is placed.

摘要： An image forming apparatus includes: a PDL analyzing unit that analyzes print data and obtains a drawing condition; a drawing unit that uses a type of dither selected from types of dither, prepared and associated with drawing conditions, according to the drawing condition analyzed, and generates output image data; an image forming unit; a fixing unit that fixes an image formed on a recording sheet by heating the image to a fixing temperature; a fixing control unit that controls the fixing temperature to a target value; and a database in which each of the types of dither is associated with the target value of fixing temperature for power saving. The fixing control unit obtains from the database the target value of fixing temperature corresponding to the type of dither used in the drawing unit and carries out control to conduct fixing at the target value thus obtained.
