Electrophotographic process control device which uses fuzzy logic to control the image density |
摘要 |
An electrophotographic process control device for controlling the supply of a toner in such a manner as to stabilize images against changes in the characteristics of a photoconductive element and in the concentration of the toner. An image density sensor measures the density of an image formed on a photoconductive drum. A scanner writes read image data representative of a document on the photoconductive drum. A determining section is responsive to the image density from the image density sensor and write image data from the scanner and representative of the area of an image for executing a predetermined fuzzy combination operation by using fuzzy rules registered beforehand and converts a membership function resulted from the operation to a non-fuzzy value to thereby determine a toner supply manipulation value.
