ABSTRACT:
A xerographic copying machine in which images of easily variable size are copied onto ordinary paper. A stationary optical system projects an optical image onto an image projection surface adjacent which a photosensitive drum is rotatably and linearly movably mounted. The photosensitive drum is rotated at an angular velocity and moved in a linear velocity in a plane parallel to the surface upon which the image is formed at speeds so that the relative linear velocity of a point on the surface of the photosensitive drum and the optical image is substantially zero. An image transferring mechanism confronts a non-image-projection surface of the photosensitive drum for conveying the paper onto which the image is transferred. The linear velocity of the paper as determined by the image transferring medium is such that there is no slippage between the surface of the paper and the photosensitive drum as the drum is moved in a plane parallel to the plane in which the image is formed.
