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.ltoreq.V1
