摘要： In an image forming method using an electrophotographic process, an amount of toner to be supplemented for maintaining a desired image density is estimated in response to input data which are a ratio of reflection densities produced by an optical sensor responsive to a pattern for control and an estimated toner consumption signal. Toner supplement control is executed on the basis of the result of estimation. The method sharply responds to a change in environment due to aging and a change in the kind of documents to thereby insure stable image density, compared to a conventional method relaying on an optical sensor or a toner sensor.

摘要： A toner density control method senses the concentration of a toner image for control formed on a photoconductive element by an optical sensor and, based on the output of the sensor, corrects a target target toner concentration for toner supplement control to be effected in response to an output of a toner concentration sensor mounted on a developing device. When the output Vs of the optical sensor is determined to be greater than a reference value Vs.sub.0 (short toner deposition), the reference value Vt.sub.0 is corrected to smaller one. When Vs determined to be smaller than Vs.sub.0 (excessive toner deposition), Vt.sub.0 is corrected to greater one. In each of such cases, a predetermined amount n.multidot..DELTA.VT is subtracted from or added to the output Vt of the toner concentration sensor of that instant.
