An image forming apparatus includes a light transmitting member provided at a reading position set in a conveyance path and an opposite plate opposed thereto, and a document being conveyed passes between this opposite plate and the light transmitting member. On an opposing surface of the opposite plate to the light transmitting member, a low brightness area, for example, like a gray color and a high brightness area, for example, like a white color, having a higher brightness than the low brightness area are formed adjacent to each other in a conveyance direction of the document. Then, an image reader sets a home position of a scanning unit to a first position or a second position corresponding to either the low brightness area or the high brightness area to read the document passing through the reading position.

An image processing system includes plural image processing devices connected with each other by a network. In the one image processing device, in a case where a new job accepted by a job accepting unit may not be executed immediately, a control unit transmits image data related to the job to the other image processing device capable of image processing and causes the other image processing device to execute image processing. In the other image processing device, the control unit assesses whether or not an image processing result is to be returned to the one image processing device, and transmits the image processing result to the one image processing device to execute a final process if assessed to return the image processing result, but executes the final process of the image processing result in the other image processing device if assessed not to return the image processing result.
