PROBLEM TO BE SOLVED: To provide a toner supply device in which a part for type discrimination of the toner supply device, a part for recognition of history of using condition, and a toner supply port switching part is configured by one member.SOLUTION: A toner supply device 20 is filled with toner of any color out of Y, M, C, K in the inside of a housing 52 and includes a cover 53 at an end part coupled to a coupling part 43 of a device main body 1. The cover 53 includes an IC substrate 44 at a left upper corner, a color setting part 46 at a right upper corner, and an opening/closing shutter 58 at a lower portion of a side surface. The IC substrate 44 constitutes a memory circuit and a drive memory circuit by electronic chip component part 61, and usage history information such as whether or not the toner supply device 20 is new, whether or not it is attached and detached in the middle of the operation, a color of toner stored, and the amount of consumed toner is read and written by a control part. The color setting part 46 constitutes a correctness recognition mechanism part which permits a correct mounting and prohibits an incorrect mounting of the toner supply device 20. The opening/closing shutter 58 is interposed between a toner supply port 57 and a toner receiving port 48 of the coupling part 43, and opens and closes a toner supply path. |
