Abstract
The present invention relates to an image forming apparatus such as a copying machine. In the image forming apparatus according to the present invention, a sealing member is interposed between a transparent platen on which an original is put and a frame member on which the transparent platen is mounted. Therefore, the sealing properties between the transparent platen and the frame member on which the transparent platen is mounted are improved, thereby to make it possible to prevent external air from entering the apparatus from a portion between the frame member and the transparent platen. As a result, it is possible to prevent image degradation and an increase in toner consumption.
