Failures of respective light emitting elements are detected without printing on a sheet. An image forming apparatus includes an optical scanning section including plural light emitting sections each including plural light emitting elements, plural photoreceptors which are provided correspondingly to the respective light emitting sections and on which electrostatic latent images are formed by emitted lights of the respective light emitting sections, developing sections to develop the respective electrostatic latent images formed on the respective photoreceptors with toners of different colors, a transfer target section to which respective images developed by the developing sections are transferred, a density detection section to detect densities of the respective images transferred to the transfer target section, and a failure determination section, in which when registration control is performed based on respective first test images transferred from the respective photoreceptors, the density detection section detects a density of a second test image formed on the transfer target section by causing a light emitting element included in a first light emitting section among the plural light emitting sections to emit light, and the failure determination section determines a failure of the light emitting element based on a detection result.
