摘要： This invention relates to an image forming apparatus which employs a recycling scheme of recovering and reusing transfer residue toner, and a convey control method for recycle toner. In order to prevent a phenomenon such as fogging or character thickening, a toner recycle mechanism shares one driving source with a photosensitive body or fixing unit, and includes an electromagnetic clutch for switching driving force transmission to the recycling means when driving the photosensitive body or fixing unit, and a controller which controls power supply to the electromagnetic clutch. The convey control method for recycle toner includes the steps of starting copying, measuring a printing ratio of an image pattern per image, and suppressing a return amount of the recycle toner when the printing ratio of the image pattern is low.
