PURPOSE: To provide an image forming device capable of maintaining high image quality, recycling toner, and effectively utilizing the device by judging the constitution of image data inputted from the outside and selectively actuating a developing system for normal developing and a developing system for recycle based on the judged result. CONSTITUTION: By a controller 34, the constitution of the image data in a RAM for image data 33a is judged on a prescribed condition by an image recognition processing routine in a printing mode. Based on the judged result, one of two developing systems is selected and actuated. That means, when there is possibility that the image is deteriorated by the recycle toner, the developing system for normal developing is used. When there is no possibility that the image is deteriorated by the recycle toner, the developing system for recycle is used. Thus, a natural resource can be effectively utilized by utilizing the recycle toner without causing such a problem that the image is deteriorated by the recycled toner. |
