Patent ID: 7620358

Claim:
A developer collecting apparatus installed in an image forming apparatus having an image carrier on which an electrostatic latent image is formed by exposure with light corresponding to image data; an intermediate transfer body to which a developer image obtained by developing the electrostatic latent image on the image carrier is transferred; a cleaning section for eliminating residual developer that remains on the image carrier without being transferred from the image carrier to the intermediate transfer body and residual developer that remains on the intermediate transfer body without being transferred from the intermediate transfer body to a transfer-subjected medium; and a casing for accommodating the image carrier, the intermediate transfer body and the cleaning section therein, the developer collecting apparatus collecting the developer eliminated from the image carrier and the intermediate transfer body by the cleaning section, the developer collecting apparatus comprising: a positioning frame for determining a mounting position of the image carrier onto the casing; a waste developer container in which waste developer eliminated by the cleaning section is stored; and a container mounting section for mounting the waste developer container so as to be removable from the positioning frame and holding the waste developer container so as to be angularly displaceable with respect to the positioning frame, wherein the container mounting section includes a biasing device for biasing the waste developer container into a predetermined angular position with respect to the positioning frame.
