Abstract:
1. An image forming apparatus comprising: an image carrying member unit which includes an image carrying member, a cleaning device that removes a toner left on the image carrying member and a toner discharge portion that discharges the toner from the cleaning device and which is configured to be inserted with respect to a main body of the image forming apparatus with one end of the image carrying member unit in a longitudinal direction thereof first and removed with respect to the main body of the image forming apparatus with another end of the image carrying member unit in the longitudinal direction thereof first; a development device which includes a developer carrying member that supplies the toner onto the image carrying member, which is arranged adjacent to the image carrying member unit, and which is configured to be inserted with respect to the main body of the image forming apparatus with one end of the development device in a longitudinal direction thereof first and removed with respect to the main body of the image forming apparatus with another end of the development device in the longitudinal direction thereof first; a developer collection mechanism which is arranged on a downstream side in a first direction in which the development device and the image carrying member unit are inserted with respect to the main body of the image forming apparatus and to which the toner discharge portion that protrudes from the one end of the image carrying member unit in the longitudinal direction is coupled; and a unit support tray which is provided such that the unit support tray is movable horizontally in the first direction and a second direction in which the development device and the image carrying member unit are removed from the main body of the image forming apparatus and which individually and removably supports the image carrying member unit and the development device, wherein the unit support tray is moved in the first direction such that the toner discharge portion moves in a direction approaching the developer collection mechanism and the toner discharge portion and the developer collection mechanism are coupled whereas the unit support tray is moved in the second direction such that the toner discharge portion moves in a direction away from the developer collection mechanism and the coupling between the toner discharge portion and the developer collection mechanism is cancelled.
