摘要： An image forming apparatus includes image forming units, a toner supply device, a common-unit detection device, an initial operation execution device, and a determination device. Each image forming unit is detachably provided in the image forming apparatus, and includes at least a development device containing toner. At least two of the image forming units are common image forming units having a common structure. When the common-unit detection device detects a common image forming unit at installation thereof, the initial operation execution device supplies a predetermined amount of toner to a development device of the common image forming unit and mixes to charge the toner by friction for a predetermined time period. Then, the. determination device detects whether the toner in the development device is charged to a predetermined level, and determines, based on the detection, whether to mix the toner one more time for another predetermined time.

摘要： In cases where the transfer positions of toner images of respective colors that are formed on respective photosensitive bodies show a positional deviation, the rpm values of driving parts that drive the photosensitive bodies are adjusted in accordance with the amount of the positional deviation so that the linear velocities of the photosensitive bodies are constant. Alternatively, in the speed setting processing in which specified reference toner images are formed on the respective photosensitive bodies at a specified timing and are transferred onto an intermediate transfer belt, and then the relative amounts of mutual positional deviation of the respective reference toner images are calculated on the basis of the timing at which the respective reference toner images are detected by toner image detection sensors, and the driving speeds of the respective photosensitive bodies are individually set on the basis of the results of these calculations.
