を特徴とする板書複写装置。[Claims for Utility Model Registration] An illumination means for illuminating the board document, a first imaging optical system including an imaging lens and a reflecting member for projecting the board document onto the photoconductor, and a first imaging optical system that projects the document image for copying onto the photoconductor. It is equipped with a second imaging optical system that is partially shared with or separate from the first imaging optical system that forms an image on the board, and both the image information written on the board and the original for copying can be processed by the selection of the optical system. A copying device capable of making copies using the same electrophotographic copying device, characterized in that the value of the developing bias of the copying device is switched between when copying a board document and when copying an original for copying.
