Abstract
An image forming apparatus that forms a color image by overlaying toner images formed on respective first, second, and third photoreceptors, comprising: first, second, and third voltage-applied members respectively facing the first, second, and third photoreceptors; a first AC power supply generating first AC voltage, and superimposing the first AC voltage on first DC voltage to generate first voltage for causing a first electric field between the first voltage-applied member and the first photoreceptor; a second AC power supply generating second AC voltage, and superimposing the second AC voltage on second DC voltage to generate second voltage for causing a second electric field between the second voltage-applied member and the second photoreceptor; and a composite circuit superimposing a composite of the first voltage and the second voltage on third DC voltage, to generate third voltage for causing a third electric field between the third voltage-applied member and the third photoreceptor.
