<P>PROBLEM TO BE SOLVED: To provide a toner storage container where the constitution of the bearing part of a rotating member arranged in a housing is made simple and compact and toner leakage from the bearing part is effectively prevented. <P>SOLUTION: A through-hole 30 is provided in the housing 5, and the shaft center part 22a of a driving input gear 22 is movably fit in the through-hole 30 from the outside of the housing 5, and fixed on a rotary shaft 18a by a fixing member 31. The bearing part 32 is provided on the outside surface of the housing 5, and a sliding surface 32a concentric with the through-hole 30 on which the outer peripheral surface of the driving input gear 22 slides is formed on the bearing part 32. A cylindrical projection part 35 protrusively provided to be concentric with the through-hole 30 and the sliding surface 32a is engaged in a groove part 36 provided to be recessed on the inside surface of the driving input gear 22 while leaving a predetermined space in between, thereby forming a communicating part 37. <P>COPYRIGHT: (C)2007,JPO&INPIT |
