Claim 7:
8. An image forming apparatus, comprising:
the developing device according to claim 7;
a developing drive motor that drives the stirring conveyance member;
a toner storage portion that stores the toner to be supplied to the developing device;
the main-body-side conveyance path that connects the toner storage portion to the toner replenishment section;
a toner supply motor that supplies the toner stored in the toner storage portion to the toner replenishment section via the main-body-side conveyance path;
a control section that controls the developing drive motor and the toner supply motor; and
a detection mechanism that detects accumulation of the toner at the connection portion,
wherein
upon the detection mechanism detecting accumulation of the toner, the control section is capable of executing the toner loosening mode in which the developing drive motor drives the conveyance member to rotate reversely together with the stirring conveyance member, and thus the developer in the developing container flows reversely to the toner replenishment section so as to cause the loosening member to reciprocate at the second position.
