摘要： An image forming apparatus includes: a developing unit forming a toner image on a photoreceptor drum; a photo sensor detecting the image density of the toner image; an operation unit calculating a relational equation between the measurement detected by the photo sensor and the development potential; a storage unit storing the relational equation; and a control unit setting up a corrected development potential to obtain a target image density for the developing unit, based on the image density of toner image patches. When high-density correction is performed, the control unit forms a multiple number of toner image patches on the photoreceptor drum based on the corrected development potential that was obtained at the time of the previous high-density correction, and sets up a corrected development potential for obtaining the target image density, based on the multiple image densities of the multiple toner image patches.
