摘要： When a cleaner is included exclusively for cleaning a transfer/transport belt to remove toner therefrom, the structure of an image forming apparatus becomes complex and the costs thereof increase. The present invention attempts to remedy this situation. Specifically, a difference between a peripheral speed relative to the transfer/transport belt to be set for cleaning and a peripheral speed relative to photosensitive drums to be set therefor is made larger than that between peripheral speeds to be set for ordinary image formation. Because of this constituent feature, unnecessary toner on the transfer/transport belt is efficiently transferred onto the photosensitive drums on a stable basis for a short period of time.

摘要： An image forming apparatus uses the difference in time taken for each patch to reach a color sensor, which occurs upon reversing the conveyance direction of a printing material. Due to this difference in time, the temperature of the printing material in detection by the color sensor differs among the respective patches. The error of a colorimetric value due to thermochromism is reduced by placing a patch with a colorimetric value which has a low temperature dependence so as to be detected earlier, and a patch with a colorimetric value which has a high temperature dependence so as to be detected later.
