Abstract
An image forming apparatus includes data conversion, charging, exposure, developer supply, image density calculation, determination and voltage change mechanisms. The data conversion mechanism converts image data into printing data. The charging mechanism charges an image carrier. The exposure mechanism forms an electrostatic latent image on the image carrier based on the printing data. The developer supply mechanism supplies a developer to the image carrier having the electrostatic latent image with an electrostatic force. The image density calculation mechanism calculates an image density of an image having a predetermined number of lines in the printing data. The determination mechanism determines whether a voltage to be applied to the developer supply mechanism is changed based on a calculation result by the image density calculation mechanism. The voltage change mechanism changes the voltage to be applied to the developer supply mechanism based on a determination result by the determination mechanism.
