PROBLEM TO BE SOLVED: To prevent toner concentration from getting high in a developing unit because of the defective circulation of the toner in facsimile equipment or the like having a cleaner toner magazine(CTM). SOLUTION: This toner supply device is constituted so that the toner of the CTM 3 is delivered from a delivery opening 54a, carried to the vicinity of a recovery opening 54b by a carrying spring 62 while being stirred by a paddle 61 in the developing unit 2 and recovered through the opening 54b by a magnet roller 51. Then, the toner in the CTM 3 is carried to the opening 54a from the opening 54b by rotating a spring 55 by the rotation of a shaft 58. Thus, since the toner is not heaped at the opening 54b, the circulation thereof becomes excellent and the toner concentration in the unit 2 is prevented from getting high. |
