[0003] In such an electrophotographic image forming apparatus, even if the printing rate of the image is low, when the toner image formed (transferred) on the printing paper has a plurality of solid areas and halftone areas, etc. In the uniform density area, during the process of fixing the printing paper at a certain temperature, there will be deviations in the dissolution mode of the toner in the uniform density area and other areas, and the image completed on the printing paper after the fixing process will also be different. May produce uneven gloss

An image forming apparatus includes a toner image forming section, a fixing section, and a control section. The toner image forming section forms a toner image based on image data for printing on printing paper. The fixing section fixes the toner image on the printing paper through thermocompression. The control section controls a toner image forming operation by the toner image forming section and a fixing operation by the fixing section. The control section calculates a size parameter associated with a size of a uniform density region included in the toner image based on the image data for the printing and controls a fixing temperature of the fixing section according to a calculation result.
Description
technical field [0001] The present invention relates to image forming devices such as printers, copiers, and compound machines. Background technique [0002] In image forming apparatuses such as printers, copiers, and multifunction machines, there is disclosed a technology for calculating the printing ratio of an image based on input image information, and controlling the amount of toner replenishment to a developing device based on the calculation result of the printing ratio. To stabilize the image quality by keeping the toner concentration in the developing unit constant. [0003] In such an electrophotographic image forming apparatus, even if the printing rate of the image is low, when the toner image formed (transferred) on the printing paper has a plurality of solid areas and halftone areas, etc. In the uniform density area, during the process of fixing the printing paper at a certain temperature, there will be deviations in the dissolution mode of the toner in the un...
