Abstract:
A toner conveying apparatus comprising: a toner conveying member which discharges toner outside a toner accommodating portion; toner conveying passage which receives toner discharged from the toner accommodating portion; and a screw constituted such that a pitch in its region downstream in the toner conveying direction is wider than a pitch in its region upstream in the toner conveying direction; and a drive device which drives the toner conveying member and the screw; wherein if a toner feeding amount per unit drive time of the toner conveying member is defines as V1, and a toner feeding amount per unit drive time in the region of the screw upstream in the toner conveying direction is defined as V2, and a toner feeding amount per unit drive time in the region of the screw downstream in the toner conveying direction is defined as V3, a relation equation of V2≦V1
