PROBLEM TO BE SOLVED: To easily stabilize, in a configuration in which a circuit for adjusting a grid voltage and a circuit for adjusting a development voltage are serially connected, the grid voltage and the development voltage.SOLUTION: An image forming apparatus includes: an electrification voltage generating circuit 200 for generating an electrification voltage applied to a wire 53; a grid voltage adjusting circuit 250 for adjusting a grid voltage generated in a grid electrode 55 after the electrification voltage is generated; and a development voltage adjusting circuit 270 for adjusting a development voltage generated in a developing device after the electrification voltage is generated. The development voltage adjusting circuit 270 is so configured as to generate a development voltage by dividing the grid voltage. Among both of the adjusting circuits 250 and 270, a response speed of an adjusting circuit on a side in which control is started later is set to be slower than that of an adjusting circuit on a side in which control is started earlier. |
