<P>PROBLEM TO BE SOLVED: To provide an image formation device that stably supplies toner from a toner supplier to a developer using a DC motor. <P>SOLUTION: An image formation device 1 includes: a DC motor 131 that can change a rotation speed per unit time by controlling the on time-of a pulse voltage to be applied; a toner residual amount calculation part 145 that calculates the toner residual amount of a toner content 120; a printing rate calculation part 141 that calculates the amount of toner used for developing as a printing rate in a formed image; a function storage section 155 that stores a function of the toner residual amount in the toner content 120 and the on-time in one pulse period per unit printing rate applied to the DC motor 131; and a control section 160 that controls the toner supply amount from the toner content 120 to a developer 2 based on the toner residual amount calculated in the toner residual amount calculation part 145, the printing rate of the output image calculated in the printing rate calculation part 141, and the function of the function storage section 155. <P>COPYRIGHT: (C)2012,JPO&INPIT |
