Abstract
In an image forming apparatus for forming an image on a sheet of paper, including an image forming device for forming a reference toner image having a predetermined density on an image retaining member. A first detector detects a density of the reference toner image formed on the image retaining member and outputs first density data for representing the detected density thereof, and then, the reference toner image formed on the image retaining member is transferred onto a sheet of paper. On the other hand, a second detector detects a density of the reference toner image transferred on the sheet of paper and outputs second density data for representing the detected density thereof. Further, a controller automatically adjusts an image density of an image formed on a sheet of paper so as to obtain a predetermined image density by controlling operation conditions of the image forming device based on the first and second density data respectively outputted from the first and second detectors.
