Image forming apparatus capable of reducing a toner consumption amount by performing toner supply control
Abstract:
In an image forming apparatus, to provide a lubrication effect for an abutment portion of a transfer belt and a belt cleaning blade, when a control toner image is supplied, the control toner image is supplied to the abutment portion even when it is not necessary, thereby consuming a large amount of toner. In the image forming apparatus, the control unit changes a toner amount of the control toner image reaching the abutment portion of a photosensitive member and a photosensitive member cleaning blade and the toner amount thereof reaching the abutment portion of a transfer belt and a belt cleaning blade, based on a detection result of an environment detection unit.
