<p>PURPOSE:To completely consume toner to the end without exerting adverse influence such as irregularity in pitch and blurring on an image by constituting a part of a developer container so that it can be deformed and allowing developer inside the container to move toward a developer carrier when the container is deformed. CONSTITUTION:This device is constituted so that the leading edge part of a paper feeding cassette 10 pushes in the soft part 5 of the toner container 5 by inserting the cassette 10 in a main body. By comparing the above state with a state where the cassette 10 is completely inserted in the main body, it is recognized that the soft part 5 of the toner container is pushed in by the leading edge part of the cassette 10 and the toner inside the container swells to envelope a sleeve 3. Especially, when the remaining amount of toner is small, the toner is more effectively supplied to the sleeve 3. Thus, printing is performed without the occurrence of void caused by the depletion of toner on the image until there is no toner in the toner container.</p> |
