PROBLEM TO BE SOLVED: To accurately determine a mixing ratio of a plurality of types of toner in a toner to be supplied to image forming parts.SOLUTION: An image forming apparatus includes image forming parts (photoreceptor drum 21, charging part 24, and exposure part 25, etc.), toner supply parts (toner container 22, supply roller 22a, and control part 50, etc.), a toner analysis part (AMS measuring part 105, etc.), and a ratio acquisition part (control part 50, etc.). The image forming parts form an image on a medium with a toner. The toner supply parts supply a mixed toner including a plurality of types of toner to the image forming parts. The toner analysis part analyzes the toner to be supplied to the image forming parts to acquire information for specifying the toner. The ratio acquisition part determines a mixing ratio of the plurality of types of toner in the toner to be supplied to the image forming parts on the basis of the information acquired by the toner analysis part.SELECTED DRAWING: Figure 4 |
