Embodiment 1
[0055] (basic structure)
[0056] First, referring to FIGS. 1-6, the basic structure of the image forming apparatus will be described. FIG. 1 is a sectional view for describing an image forming apparatus, and FIG. 2 is a sectional view for describing a main part of a process cartridge used by the image forming apparatus. Figure 3 is a perspective view illustrating the image forming apparatus, and Figure 4 is a perspective view illustrating how the process cartridge is loaded into or removed from the image forming apparatus. 5 is a sectional view illustrating how a process cartridge as an image forming unit is loaded into or removed from the image forming apparatus, and FIG. 6 is a perspective view illustrating how a toner container is loaded into or removed from the image forming apparatus.
[0057] Referring to FIG. 1, in a main assembly 1 of an image forming apparatus, an original reading portion 2, a laser scanner 4, a process cartridge and a sheet feeding cassette 10 are ...
Embodiment 2
[0101] A second embodiment of the present invention is described below. Incidentally, the basic structures of the image forming apparatus and the process cartridge in this embodiment are the same as those in the first embodiment, and therefore, will not be described again here.
[0102] 16 is a partially cutaway front view of a mechanism in the image forming apparatus for opening or closing a cover of the image forming apparatus. 17-20 are diagrams for describing the relationship between elements of the mechanism in different stages of opening or closing the process cartridge cover 102 for replacing the process cartridge and opening or closing the toner container cover 20 for replacing the toner container. view. In each drawing, (a) is a front view of the mechanism, and (b) is a sectional view of the mechanism along a plane F-F in FIG. 16 . Figure 21 is a control table for determining the hook position based on the state of the photosensitive element of the cover position de...
Embodiment 3
[0133] This embodiment of the present invention is intended to solve the following problems which arise when a toner bottle detachably mounted in a process cartridge has a handle for mounting or detaching the toner bottle.
[0134] That is, since the handle protrudes from the end face of the toner bottle, even when the toner bottle is housed in the process cartridge, the longitudinal end face of the handle-mounted toner bottle remains exposed. Therefore, when the process cartridge is taken out to remove jammed recording paper or replace the drum cartridge, a protruding handle is likely to be provided in the inner wall of the main assembly of the image forming apparatus through a hole through which the toner bottle can be inserted or pulled out. The edge of 314c or the guide for guiding the process cartridge when installing or detaching the process cartridge is caught.
[0135] Specifically, as shown in FIG. 34, the end surface of the toner bottle is provided with a large handl...
