Abstract
An image forming apparatus for electrifying a surface of a photoreceptor with the use of an electrification member includes: a first output unit configured to output a first AC voltage; a second output unit configured to output a second AC voltage having the same frequency as a frequency of the first AC voltage and having a phase different from a phase of the first AC voltage; a superimposition unit configured to superimpose, on a DC component, an AC component containing at least one of the first AC voltage and the second AC voltage; and an application unit configured to apply a voltage that has been subjected to superimposition by the superimposition unit to the electrification member, wherein the superimposition unit changes the AC component to be superimposed on the DC component at a predetermined timing.
