Abstract: A printer detects density of a toner pattern on an intermediate transfer belt, operates a differential value for the detection value, and compares the differential value with a threshold value. If fluctuation of detection values is great and there are detection values of which differential values exceed the threshold value, those detection values are assumed to contain noise due to abnormality of the shape on the belt, and the detection values in such a range are corrected using curve approximation. A tone correction table is updated using the corrected detection values.

Abstract: 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.
