<p>An image forming apparatus comprises image forming stations Y, M, C, K for respective colors arranged along a transfer belt 16, each image forming station including an image carrier 20, a charging means 22 and a developing means 24 disposed around the image carrier 20. The apparatus further comprises a housing body 2 in which said image forming stations and said transfer belt are situated, a support frame 9a for supporting roller 14 around which said transfer belt is laid with some tension, and an image density detecting means 18 which is arranged to face said transfer belt, wherein said support frame is attached to the housing body such that the support frame is detachable relative to the housing body by means of pivotal movement. The apparatus has a locking means 9c for locking said support frame to the housing body, wherein said image density detecting means is disposed in proximity to said locking means, thereby preventing the deterioration of the detecting accuracy of the image density detecting means. <IMAGE></p> |
