An image forming apparatus includes an image forming unit, a control unit, a reading unit, an analysis unit, a storage unit, and a computation unit. The image forming unit forms an image on a sheet. The control unit controls the image forming unit. The reading unit reads the sheet. The analysis unit analyzes a reading result acquired by the image formed on the sheet being read by the reading unit, and outputs an analysis result. The storage unit stores a printing condition used when the image was formed and the analysis result in association with each other. The computation unit computes a control parameter to be used by the control unit in order to control the image forming unit, with reference to the analysis result and the printing condition stored in the storage unit.
