摘要： There is provided an image forming device, including: a first electrical load; a second electrical load; a voltage generation circuit that generates a second voltage to be applied to the second electrical load; a shunt circuit that located between an output side of the voltage generation circuit and the first electrical load; and a controller that executes first control of controlling the shunt circuit to change a first voltage applied from the shunt circuit to the first electrical load to a first target level, and second control of controlling the voltage generation circuit to change the second voltage to a second target level. The controller executes voltage change suppression control of controlling the second voltage such that change of the second voltage becomes gentler as a difference between the first voltage and the first target level becomes larger.
