A collection vessel 124 is formed with a plurality of collection spaces 148a to 148f separated by partition walls 146, and collection ports 134 and 136 are connected to the collection spaces 148a to 148f. The collection spaces 148a to 148f are made to communicate with each other through a communication part 152. A developer intake section 154 implementing a full condition detector is placed below the communication part 152. A detection vessel is placed in the developer intake section 154 for detecting a full condition based on the developer overflowing the collection spaces 148a to 148f.
