Abstract

A portable photocopier comprises an elongate housing (10) accomodating a roll of sensitised paper (25) and a feed mechanism for feeding the paper from the roll passed a corona wire (39) for electrostatically charging the paper to a location (13) for illuminating the charged sheet in contact with a document to be copied and then to a device (28) for applying toner to the charged exposed paper and for fixing the toner. The copier is traversed across the surface of the document to be copied by the movement of the paper.
