Abstract
A laser printing process using a rotary light sensitive roller electrically charged by points by a laser beam and intended for receiving onto the charged points particles of a toner powder and then transferring the same onto a band to be printed, includes a first step wherein the image to be printed is stored, by a first laser beam coming from a first laser source controlled by a computer, onto a rotary memory roller whose surface is covered with a layer of a material capable of assuming either an amorphous or a crystalline structure, this structure being convertible under the action of a laser beam, and this material showing a high difference in reflecting ability according to whether it assumes the one or the other of its structures, and includes a second step wherein the thus stored image is transferred, by the optical reflection of a second laser beam coming from a second laser source having in its whole a linear character, onto the light sensitive roller intended to receive the toner and to transfer the image onto the band to be printed.
