像形成装置。[Scope of Claim for Utility Model Registration] In an image forming apparatus equipped with a feeding means for feeding a sheet member placed on a mounting table to an image forming section, a path along which the sheet member is fed by the feeding means; Along the way, a detection means is provided to detect the reflection density of the surface of the sheet member being fed on which a new image is to be formed, and a holding means is provided to hold the reflection density value detected by the detection means. and a comparison means for comparing the held reflection density value with a predetermined set value, and when the comparison means determines that the surface has already been imaged, the image forming process is stopped. An image forming apparatus characterized by:
