Alternatively, the process cartridge assembly includes four process cartridges 1, and the developing cartridges 20 of the four process cartridges 1 are for containing toner of different colors.

Among them, three process cartridges 1 are provided with fitting units, and one process cartridge 1 is not provided with a fitting unit.

As shown in fig. 5, the fitting units of the three process cartridges 1 include, in the front-rear direction of the accommodating member 2, a first unit, a second unit, and a third unit in this order, the first unit, the second unit, and the third unit being for distinguishing by positions on the holders 31 of the process cartridges 1 and widths in the width direction of the holders 31 of the process cartridges 1. The accommodating member 2 is provided with four placement grooves 201. The color of toner contained in the process cartridge 1 corresponding to each of the placement grooves 201 is fixed, which may cause the image forming apparatus to fail to operate properly when the process cartridge 1 is misplaced on the containing member 2.

In an alternative embodiment, the width of the first unit is larger than the width of the second unit in the width direction of the holder 31 of the process cartridge 1, the width of the second unit is equal to the width of the third unit, and the positions of the first unit, the second unit, and the third unit in the width direction of the corresponding holder 31 are different from each other.

The process cartridge abutting against the back bezel 23 of the accommodating member 2 in fig. 5 is a process cartridge without an assembly unit.

In an alternative embodiment, four placement grooves 201 are provided on the accommodating member 2, three placement grooves 201 of the four placement grooves 201 are provided with the fitting portions 2011, one placement groove 201 is not provided with the fitting portions 2011, three placement grooves 201 provided with the fitting portions 2011 correspond to three process cartridges with assembly units one by one, and one placement groove 201 without the fitting portions 2011 corresponds to one process cartridge without the assembly units. As shown in fig. 6, when the four process cartridges are placed at the correct positions on the accommodating member 2, the four process cartridges are uniform in height on the accommodating member 2, and the accommodating member 2 can be normally pushed into the apparatus body; as shown in fig. 7, when a process cartridge is placed at a wrong position on the accommodating member 2 among the four process cartridges, one or more process cartridges may have different heights, the process cartridge on the accommodating member 2 may interfere with the device body, and the accommodating member 2 cannot be pushed into the device body, so that it can be visually found that the process cartridge 1 is misplaced on the accommodating member 2, and the accommodating member 2 does not need to be pulled out again to place the process cartridge again, which makes the operation simple and improves the user experience.

It should be noted that four placement grooves 201 are provided in the accommodating member 2. The color of toner contained in the process cartridge 1 corresponding to each of the placement grooves 201 is fixed, which may cause the image forming apparatus to fail to operate properly when the process cartridge 1 is misplaced on the containing member 2.

It should be noted that the process cartridge of the prior art is not only put on the accommodating member 2 reversely but also put on the wrong side because it has no assembly unit. Whether the placement groove 201 of the conventional process cartridge in the housing member 2 is correct or not is determined by recognizing the chip position of the process cartridge by the apparatus body of the image forming apparatus. When the positions of the process cartridges on the accommodating member 2 are all correct, the image forming apparatus can operate normally; when the process cartridge on the accommodating member 2 is misplaced, the image forming apparatus cannot normally operate, and at this time, the accommodating member 2 needs to be pulled out again to replace the process cartridge, so that the operation is very cumbersome, and the user experience is reduced.

Because the processing box 1 that has the assembly cell of this application and the standing groove 201 one-to-one on the hold component 2, processing box 1 is placed behind wrong standing groove 201, assembly cell and cooperation portion 2011 can appear not cooperating, lead to its processing box can't install to target in place, thereby hold component 2 can't push into inside the device body, consequently can audio-visually discovery processing box 1 misplaces on hold component 2, need not pull out hold component 2 again, the processing box is placed again, make easy operation, user experience sense has been improved.

As shown in fig. 6, an embodiment of the present invention provides an image forming apparatus including an apparatus body and a process cartridge assembly; the device body is provided with an accommodating part 2, and the process cartridge assembly is detachably placed on the accommodating part 2.

The embodiment of the present invention provides an image forming apparatus, a processing box assembly of the image forming apparatus, and a processing box assembly of the image forming apparatus, wherein the processing box assembly has the same structure as the processing box assembly, and can bring about the same or similar technical effects, which are not repeated herein.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
