摘要： A method of forming an electric signal wherein the signal level corresponding to the selected color in the original indicates the maximum or minimum value. The original is exposed to the light and the reflected light is introduced into a photoelectric converting means through two different paths, each of which has a filter corresponding to a different selected color. These two signals are multiplied by a predetermined ratio, and are combined to obtain the final image signal.

摘要： An image forming apparatus which detects deterioration of developer contained in a developing unit, and if it is the case, the toner is discharged out of the developing unit through a surface of an image carrying member. The apparatus is provided with a sensor to measure toner concentration in developer contained in the developing unit, a drive controller to control a supply amount of toner into the developing unit based on the toner concentration, a calculating unit to obtain average toner supply during a predetermined period, a detecting unit to detect the deterioration of the developer by comparing the average toner supply with a reference data stored in a memory.

摘要： The present invention relates to a color copying apparatus which prevents toner scattering from a tip portion of a cleaner to an image area of an image carrying drum. An exposing device forms a stripe latent image in a stripe area at an upstream of the image area of an image carrying drum in a rotating direction of the image carrying drum, and a developing device stops development within the stripe area. The result is a generation of a sharp potential gap in the stripe area. The cleaner starts cleaning by touching to the stripe area, and accumulated toner on the tip of the cleaner is attracted by the sharp potential gap and is held within the stripe area. This prevents the toner from being scattered to the image area of the image carrying drum.
