Abstract
This invention provides an apparatus for reproducing image from a microfilm, in which a microfilm having a negative or positive image is illuminated by illuminating image and projecting thus illuminated microfilm image onto a photosensitive member. The reproducing apparatus is provided with a charger for positively or negatively charging the surface of the photosensitive member, measuring device for measuring the light intensity from thus illuminated microfilm, and charge controller for selecting the polarity of charge to be given to the photosensitive member in response to the result of measurement by the measuring device thereby providing a positive reproduced image regardless whether the image on the microfilm is negative or positive. In another embodiment the apparatus is provided with development controller for selecting toner for image development on the photosensitive member in response to the result of measurement by the measuring device.
