    摘要: An image forming apparatus for forming images on a recording medium on the basis of an electrophotography system includes a calculator for determining the quantities of state and quantities of control using fuzzy sets and for calculating, for each color, quantities of control. Each quantity of control corresponds to one of the detected quantities of state from a degree to which the quantity of state belongs to each fuzzy set. An extractor for extracting, in accordance with predetermined rules, a main quantity of control for each color in a specific position within the area represented by each quantity of control calculated by the calculator.

    摘要: According to the present invention, an image forming apparatus comprises an image forming unit for producing an image on paper, a detector for detecting a plurality of parameters indicating a state of the image forming unit, a corrector for correcting the state of the image forming unit, a rule memory for storing rules for determining the relation between the parameters and the timing of operation of the corrector, and a control for controlling the corrector according to the parameters the detector detects and the rules stored in the memory. Therefore, even a simple configuration permits high-precision control. This reduces a time loss due to the correcting operation, minimizes consumption of development agent, and thus ensures constant gradation all the time.
