Abstract
An image forming apparatus includes an original document conveying device to convey an original document at a predetermined conveying speed according to a magnification ratio. An original document reading device reads image information of the original document with a one-dimensional image sensor, and an information omission device omits information of the image information of the original document read by the original document reading device. An image forming device forms an image according to the image information read by the original document reading device synchronized with conveying of the original document by the original document conveying device. An original document protect mode designating device designates an original document protect mode, and an original document protect mode processing device reduces the predetermined original document conveying speed of the original document conveying device by 1/n and causes the information omission device to omit information of every (n-1) number of lines of the image information read by the original document reading device in a sub-scanning direction when the original document protect mode is designated by the original document pro…
