Abstract:
A collection vessel 124 has a shutter 138 for opening and closing collection ports 136. A rotation shaft 140 of the shutter 138 is provided with an opening/closing piece 144. The opening/closing piece 144 abuts a protrusion on an image formation apparatus main unit and opens the shutter 138 largely so that a discharge section inserted into the collection port 136 does not abut. The collection port 136 is made a long hole so as to allow the discharge section to move. Further, the shutter 138 is formed integrally with a plurality of door parts 142 so as to open or close the collection ports 136 by one operation.
Abstract:
A collection vessel 124 has intermediate transfer body collection ports 134 and developing machine collection ports 136. Collected developer occurrence sections placed in intermediate transfer bodies and developing machines are connected to the collection ports 134 and 136. At least two of the collection ports 134 and 136 are formed so that they are arranged in a longitudinal direction. Collection spaces 148a to 148f to which the collection ports 134 and 136 are connected are separated by partition walls 146, and the collection capacities of the collection spaces 148a to 148f are set according to the heights and shapes of the partition walls 146.
Abstract:
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.
