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.

Method and apparatus for correcting image formation using fuzzy logic

An image forming apparatus includes a movable image bearing member; an image forming device for forming an image on the image bearing member; transfer charging device for transferring an image from the image bearing member onto an image receiving material at an image transfer position; a detector for detecting an ambient condition of the apparatus; a controller for controlling an output of the transfer charging device in accordance with an output of the detector, wherein the output of the transfer charging device is a function of the output of the detector; and a correcting device for correcting the function.

Image forming apparatus

An image forming apparatus includes a movable image bearing member; an image forming device for forming a toner image on the image bearing member; a transfer device for electrostatically transferring the toner image from the image bearing member onto a transfer material at an image transfer position; a transfer material carrying device for carrying the transfer material to the transfer position; wherein the transfer device supplies different electric charge amount per unit area to an end of the transfer material in a direction of conveyance of the transfer material by the transfer material carrying device and to another portion of the transfer material.
