Image forming apparatus with deflection amount detector and toner density detection means
The image forming apparatus includes a loop amount detection sensor, disposed between a secondary transfer part and a fixing part, for detecting a loop amount of a transfer material by detecting a reflection of light radiated on the transfer material, a density detection sensor for detecting a density of a toner image that is primarily transferred to the intermediate transfer belt with the primary transfer roller, and a loop control part for controlling the loop amount of the transfer material based on the density of the toner image that is detected by the density detection sensor and the loop amount that is detected by the loop amount detection sensor. Accordingly, the image forming apparatus attains higher accuracy in the deflection amount detection by performing the deflection amount detection at least with the dependency of the image formed on the transfer material mitigated.
