A toner recovery device having a non-magnetic rotary member, magnets embedded around the circumferential surface of said non-magnetic rotary member, and an endless belt wound on said rotary member so as to recover a toner collected by a cleaning device into a developing unit. A plurality of protuberances are equidistantly and projectingly formed around the circumferential surface of said rotary member to prevent said endless belt from floating as a whole.
