<p>The invention provides an image forming apparatus and a method of manufacturing thereof which is capable of continuously forming images with proper density without reducing the image forming speed and, retrains toner consumption. A CPU for calculating an image forming condition by a density sensor (9) is provided. The image forming operation is conducted in basis of a calculated new image forming condition and a current image forming condition used prior to the calculation of a new image forming condition in the image forming operation so as to determine an available image forming condition, so that the current image forming condition is brought to the new image forming condition through a gradual change. <IMAGE></p> |
