Abstract
Abstract A portable image forming apparatus includes an image data generator and an image forming element. The image data generator includes a scanner for scanning a document, a converter for converting light reflected from the document into an elecrical signal. The image forming element includes a thermal head for forming an image on an image receiving medium, which is conveyed by a conveyer, in accordance with the electrical signal. The thermal head is positioned above the conveyer.
