Patent Images
1. An image forming apparatus comprising:
- a main assembly;
a developing device removable from said main assembly and including a developing container provided with a discharge opening for permitting discharge of a developer and a feeding member for feeding the developer in the developing container;
a driving device for driving the feeding member;
a controller for controlling said driving device; and
an outputting portion for outputting information providing an instruction to remove said developing device or information about abnormally of said image forming apparatus,wherein the developing container includes an accommodating portion for accommodating the developer and a discharging portion for feeding the developer to the discharge opening by being connected to the accommodating portion,wherein the feeding member is constituted by integrally connecting a main feeding portion, provided in the accommodating portion, for feeding the developer in the accommodating portion toward the discharging portion, a sub-feeding portion for feeding the developer in an opposite direction to a developer feeding direction of the main feeding portion in front of the discharging portion in the accommodating portion, and a discharging feeding portion, provided in the discharging portion, for feeding toward the discharging opening the developer fed from the accommodating portion to the discharging portion over the sub-feeding portion, andwherein said controller drives said driving device for a predetermined time when the information is outputted from said outputting portion.
