Image forming apparatus

Abstract

An image forming apparatus includes: multiple intermediate-transfer-member density sensors that are disposed in the axial direction of an intermediate transfer member and that detect corresponding densities of a developer image having been subjected to first transfer onto the intermediate transfer member; and a processor configured to: in response to occurrence of a variation of density on a recording medium, if a relationship between the highest density value and the lowest density value among the density values detected by the respective intermediate-transfer-member density sensors indicates a first density state, output information indicating that the variation of density is caused in a process of or after a second-transfer process in which the developer image having been subjected to first transfer onto the intermediate transfer member is transferred onto the recording medium; and if the relationship indicates a second density state opposite to the first density state, output information indicating that the variation of density is caused in a process before the second-transfer process.
