PROBLEM TO BE SOLVED: To provide an image formation apparatus which comprises a plurality of photoreceptors and brings a blade into contact with each photoreceptor, and in which a frictional resistance can be reduced between the photoreceptor and the blade and variations in a reduction effect due to the position of the photoreceptor can be suppressed.SOLUTION: A printer 100 comprises a plurality of process parts 50Y, 50M, 50C, 50K and a fixing unit 8. Each process part includes a photoreceptor 51, a developing unit 54 and a blade 56. The printer 100 executes a toner supply operation for supplying toner to the developing unit 54 while no printing of a printing job is performed. In the toner supply operation, the printer 100 increases the supply amount of toner supplied per a prescribed rotation number of the photoreceptor 51 for the process unit closer to the fixing unit 8.SELECTED DRAWING: Figure 4 |
