Verfahren zur Steuerung der Tonerdichte eines Starterentwicklers in einem Gerät zum Erzeugen von Abbildungen

摘要

The present invention provides a start developer wherein an output voltage (Vx) of a sensor in the start developer having a particular toner density is not less than 0,9 times an output voltage (Vx) of the sensor in a developer having the same toner density in a time period during which image characteristics are stabilized after repeated image formation by an image forming apparatus and is less than a threshold value (VT) at which the supply of toner is started, and a method of controlling the toner density using the start developer. According to the present invention, good images can always be formed irrespective of the variation in characteristics between sensors in image forming apparatus and from an early stage of image formation to a stable time period.
