摘要： An apparatus includes a system controller which calculates a ratio of a first signal to a second signal and adjusts a control parameter of an electrophotographic reproduction process so that the density of fog indicated by the ratio is within a predetermined range. A first optical sensor outputs the first signal by detecting a reflectance of a non-image area on the photoreceptor between a developing unit and a transfer charger. A second optical sensor outputs the second signal by detecting a reflectance of a surface of the photoreceptor between a cleaning unit and a charger. The system controller controls developer including toner and carrier to be agitated when the ratio obtained after adjusting the control parameter is still outside the predetermined range. Since the density of fog is detected with accuracy by calculating the ratio, copy quality is stabilized even when temperature changes. Moreover, even if the ratio is outside the predetermined range as a result of the supply of toner which has deteriorated due to a heat history, the deterioration of toner is restored by agitating the developer. It is thus possible to prevent copy quality from being degraded.

摘要： A process control apparatus of electrophotographic apparatus has an optical sensor for optically detecting the density of toner patches formed on a photoreceptor drum. The present apparatus is further provided with a control device for controlling lamps for the copying process, chargers and other elements. A toner patch is formed on the photoreceptor so as to be located between every two toner images for a copying operation. The control device controls the lamps, chargers and other elements in accordance with the result of the toner patches detected by the optical sensor so as to stabilize the copying picture quality. With the arrangement, it is avoided that the job efficiency during the copying operation deteriorates, and the control data obtained from the toner patches is soon used for the toner image formation for the copying operation, thereby ensuring that the process control improves in accuracy.

摘要： An image forming apparatus can prevent printed images from being degraded in image quality due to failure of the toner concentration to fall within a proper range, by correcting the deviations of the amount of toner consumption and the amount of toner supply depending on the individuality of each image forming apparatus and that enables exact identification of the cause of a fault associated with toner concentration, as well as providing an image forming method using the apparatus. A toner supply device supplies toner to a developing vessel through an opening in accordance with an instruction from a controller. The presence or absence of toner falling is detected based on the variation of the output from a magnetic permeability sensor when toner is supplied. The controller monitors the output voltage level of the magnetic permeability sensor and adjusts the input gain in accordance with the output voltage level to thereby control toner concentration.
