Abstract:
An image forming apparatus including an image carrier that includes a photoconductive layer on which an electrostatic latent image is formed, a charging member that comes in contact with the image carrier and charges the photoconductive layer, and a feeding section that supplies a current to the charging member by applying a vibration voltage with an alternating current component superposed on a direct current component, wherein the alternating current component may contain a first amplitude that eliminates charging non-uniformity when the vibration voltage is applied with a uniform amplitude and a second amplitude that is smaller than the first amplitude.
