PROBLEM TO BE SOLVED: To provide an image forming apparatus in which a developing bias for making image density unevenness (image density difference) generated in the swing period of a developing sleeve inconspicuous in any of image densities can be set. ! SOLUTION: An image forming apparatus 100 includes a developing device 4, a developing bias power supply 63, a density sensor 31, and a controller 50. The controller 50 determines, on the basis of the detection result of detecting at least one of a halftone image and a solid image developed by the developing device 4 by the density sensor 31, whether or not the other is detected and performs control so as to correct the developing bias, on the basis of the detection result of at least one of the halftone image and the solid image. !
