PROBLEM TO BE SOLVED: To provide a developer recovery device that facilitates recovering a developer remaining in a used developing device. SOLUTION: A developer recovery system includes a developing device 10 and a developer recovery device 38. The developing device 10 includes a developer device housing 12 which stores a developer, a magnetic roller 20 which has magnetic poles for carrying a developer to outside the developing device housing 12 and can rotate, a sleeve 22 which covers a periphery of the magnetic roller 20 and can rotate, and a switching mechanism 18 which switches between a state wherein the magnetic roller 20 can rotate and a state wherein the magnetic roller 20 can not rotate. The developer recovery device 38 includes a recovery device housing 40 to which the developing device 10 can be attached, a push-up pin 46 which holds the magnetic roller 20 in the rotatable state when the developing device 10 is attached, and a sleeve lock 50 which holds the sleeve 22 in a rotation stopped state when the developing device 10 is attached.
