A copying apparatus for continuously reproducing images on a web of copying paper is described. The apparatus is characterized by a web feed means which includes a carrier member adapted to engage the web in the feed direction. The carrier is capable of being moved backwards and forwards at an amplitude which may be changed by the setting of a means for determining the size of the image field on the web so that the feeding distance, during each cycle of movement of the carrier, is equal to the length of the image last exposed in the longitudinal direction of the web and, if desired, also a length of unexposed web for outwardly projecting edge portions.
