して露光し、それによつて形成した画像を他に転
写し感光体を繰返し画像形成に使用する転写型画
像形成装置であつて、 異なる分光分布を持つ複数の光源を前記原稿画
像を照明する位置へ適宜移動させられるように設
けてあり、 照明位置にない光源の少なくとも１つを利用し
て感光体をイレース処理するイレース光学系を形
成した ことを特徴とする転写型画像形成装置。[Claims for Utility Model Registration] A transfer type in which the image of a document placed on a document table is projected onto a photoreceptor and exposed to light, the image thus formed is transferred to another, and the photoreceptor is repeatedly used for image formation. The image forming apparatus is provided with a plurality of light sources having different spectral distributions so as to be moved appropriately to a position where the original image is illuminated, and the photoreceptor is illuminated by using at least one of the light sources that is not at the illumination position. A transfer type image forming apparatus characterized by forming an erase optical system for performing erase processing.
