Abstract
Abstract An image forming apparatus having an input section for inputting handwritten characters and a character recognition device for recognizing the character types in the handwritten characters inputted from the input section. Character pattern data is generated representing the character types recognized by the character recognizing device. A scanning device scans an original document image and forms an image produced by combining character pattern data generated by the generating device with the scanned image of the original document.
