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