PROBLEM TO BE SOLVED: To prevent abnormal sound produced when toner is conveyed by enhancing lubricity at a contact part of a toner conveying coil with a toner conveying pipe in a toner conveying device. SOLUTION: When the toner collected from a photoreceptor by a cleaning device is conveyed to the outside of the cleaning device by the toner conveying device structured to support the toner conveying coil 4 in a cantilever manner in the toner conveying pipe, grease is applied all over the outer peripheral end of the spiral coil 13 of the toner conveying coil 4 with a brush, and the toner is conveyed by rotating the toner conveying coil with the grease at the contact part of the outer peripheral end of the spiral coil 13 with the inner surface of the toner conveying pipe.
