Image forming apparatus for controlling the image density of a toner image

摘要

An image forming apparatus includes an image forming device for forming an image which is capable of forming a toner image (T) for density detection, and a detector (12) for irradiating light (L1) to the toner image (T) for density detection and detecting light (L3) obtained from the toner image for density detection, in which: the image forming device is controlled based on an output from the detector (12); the toner image (T) for density detection includes a first toner image (Tc) and a second toner image (Tk) having a light reflectance lower than that of the first toner image (Tc); and the detector (12) detects the first toner image (Tc) formed on the second toner image (Tk) in the case where a density of the first toner image (Tc) is detected.
