Abstract
A controller, which is a high-voltage power supply apparatus, includes: a secondary transfer high-voltage output device including a first high-voltage generator, which is configured to generate a first voltage having a positive voltage value, and a second high-voltage generator, which is connected in series to the first high-voltage generator, and is configured to generate a second voltage, the secondary transfer high-voltage output device being configured to output an output voltage, which is a sum of the first voltage and the second voltage; and a secondary transfer high-voltage control device, which is configured, in a case where the high-voltage power supply apparatus is switched from a state in which the first high-voltage generator is driven to output a first target voltage as the output voltage, to a state in which a second target voltage is output as the output voltage, to perform feedback control on the second voltage.
