<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus constituted so that the prescribed control of the near end of toner judging processing, a toner-end judging processing and a toner replenishing processing, etc., required in accordance with the toner consumption can be accurately performed by accurately reflecting the toner consumption by surface staining to the toner consumption from each color developing apparatus 31K, 31C, 31M and 31Y to a photoreceptor 11. <P>SOLUTION: As for the image forming apparatus, a main control part is constituted so that the prescribed control is performed based on the detection result by a P sensor 17, that is, the detection result as for the quantity of toner sticking to the non-image part on the photoreceptor 11. Then, the prescribed control of the toner near end judging processing, etc., required in accordance with the toner consumption from each color developing apparatus 31K, 31C, 31M and 31Y to the photoreceptor 11 is accurately performed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
