Abstract

Abstract An image forming apparatus comprises a document table for holding a document to be read, and a scanner unit for reading the image of the document while being held. The scanner unit comprises a spot light source illuminates the document and an image sensor receives the light reflected from the document and generates image signals. The image forming apparatus further includes a moving mechanism for moving the scanner unit in a first direction in which the spot light source illuminates the document and in a second direction perpendicular to the first direction, a platen for supporting an image-receiving material, a line-shaped recording head disposed facing the platen, and a controller for controlling the line-shaped recording head to form a reproduced image on the image-receiving material supported on the platen on the basis of the image signals generated by the scanner unit.
