ABSTRACT:
An image forming apparatus includes: a first image-bearing member, an intermediate transfer member for receiving an image formed on the first image-bearing member and transferring the image onto a second image-bearing member, pattern-forming means for forming a prescribed pattern on the intermediate transfer member, density detection means for detecting a density of the pattern, and control means for controlling image forming conditions based on the detected density. The intermediate transfer member is set to have a reflectance of 10-70% for light having a wavelength in the range of 700-1500 nm at least in a region thereof for forming the prescribed pattern. As a result, the pattern density detection is suitably performed on the intermediate transfer member for all of yellow, magenta cyan and black, and the detected density data is used for controlling the image forming conditions.
