Abstract

To provide a toner recovery apparatus including: a toner transporting duct; and an endless toner transporting belt; wherein the toner transporting belt is rotated in a loop form in such a way that it descends in a region where the outer circumferential surface faces a ceiling surface of the toner transporting duct and that it rises in a region where the outer circumferential surface of the toner transporting belt faces a bottom surface of the toner transporting duct, the toner recovery apparatus transports the residual toner to the outlet by holding the toner by the convex parts, spaces formed between convex parts and the bottom surface of the toner transporting duct, and the toner comprises a binding resin, releasing agent, coloring material and external additive, and torque T (mNm) measured by torque measurement method using a conical rotor in a space ratio of 50% to 60% is 1.0 to 2.5.
