摘要： An electrophotographic image forming apparatus includes a developing device including a developer reservoir for accommodating a mixed developer. The mixed developer includes a plurality of types of toner having a generally identical hue and different reflection densities. The apparatus also includes a replenishment device having a plurality of toner containers each accommodating one of the plurality of types of toner for replenishing the plurality of types of toner to the developer reservoir; a first detector for detecting whether each of the toner containers is completely empty of toner; and a second detector for detecting whether the developer reservoir is nearly or completely empty of mixed developer. A controller controls the replenishment device and allows or prohibits a printing operation based on the detection result of the first and the second detectors.

摘要： A tandem-type color image forming apparatus forms a toner pattern and toner markers on an intermediate transfer member. Tone levels in the toner pattern vary in a sub scanning direction, and the toner markers which are a same color with the tone pattern each oppose, in a main scanning direction, a different one of the tone level portions in the toner pattern, each tone level portion representing a different one of the tone levels. Positions of the toner markers in the sub scanning direction are determined to detect densities in the toner pattern corresponding to the determined positions. Tone of image data is corrected in an image formation based on a relationship between the densities and the tone levels corresponding to the determined positions.
