When being 0, image forming apparatus 1 can be printed.
The technical effect of the image forming apparatus 1 of above structure will be illustrated next.When being mounted on Delevoping cartridge in toner Cartridge 9
When Delevoping cartridge 8 being mounted on apparatus body 2 in the state of 8, it is possible to which toner Cartridge 9 is not mounted on Delevoping cartridge 8, toner sufficiently
Box 9 is centrally located.
Here, illustrate the problem of assuming when toner Cartridge 9 does not have shelter wall 150.As shown in figure 14, as toner Cartridge 9B
When without shelter wall 150, when being located at the first middle position, the light L that light-emitting component 13 is issued cannot be blocked.At this point,
The light L issued from light-emitting component 13 reaches light receiving element 14 via the downside of gear cap 100 (referring to shadow part A1).Therefore,
When toner Cartridge 9B is located at the first middle position, control unit 10 is judged as YES in the step S13 of the flow chart of Figure 13, will be driven
Power is input to toner Cartridge 9B (S14).Then, control unit 10 is judged as YES in the step S16 of the flow chart of Figure 13.Also
It is to say, although being mounted with new product toner Cartridge 9B, control unit 10, which is judged as, does not install toner Cartridge 9B (S17).Then, although
It is judged as that new product toner Cartridge 9B is not installed at Delevoping cartridge 8, but detects gear 190 and rotated according to driving force, to detects tooth
Wheel 190 is located at the second position.Therefore, even if being then installed position for what toner Cartridge 9B was properly mounted at Delevoping cartridge 8,
Toner Cartridge 9B can not be judged as new product by control unit 10.
In contrast, in the image forming apparatus of present embodiment 1, when being mounted on Delevoping cartridge 8 in toner Cartridge 9
When Delevoping cartridge 8 being mounted on apparatus body 2 under state, when toner Cartridge 9 be located at installation starting position and be installed position it
Between position, and be located at when in terms of predetermined direction first opening 15A with second be open 141 nonoverlapping positions, i.e., first
When middle position, shelter wall 150 blocks the light L of the sending of light-emitting component 13.Therefore, when detection gear 190 be located at first position
Toner Cartridge 9 be not properly attached in the state of Delevoping cartridge 8, when Delevoping cartridge 8 is mounted on apparatus body 2, be able to detect that
Toner Cartridge 9 may deviate from correct installation site.
For example, when the light L of the sending of light-emitting component 13 is not detected in light receiving element 14 in new product detection control, control
Portion 10 can notify to indicate to may be toner Cartridge 9 not being that new product or toner Cartridge 9 are mounted on from correct installation site and deviate
Position in any situation information.As a result, user be able to confirm that toner Cartridge 9 whether be new product and/or its
Installation condition.
When light receiving element 14 detects light L that light-emitting component 13 issues in new product detection control, and even if adjusting
After toner cartridge 9 receives driving force from Delevoping cartridge 8, light receiving element 14, which also continues to test in predetermined time length, to shine
When the light L that element 13 issues, control unit 10 can notify to indicate that toner Cartridge 9 is not installed at the information of Delevoping cartridge 8 to user.
Therefore, user, which can be noted that, forgets to install toner Cartridge 9.

First opening 15A and the second opening 141 are overlapped into light receiving element 14 and can receive the degree of light；And (2) first opening
The opening of 15A and second 141 deviates the degree that light cannot be received at light receiving element 14.
(1) feelings that light receiving element 14 can receive the degree of light are overlapped into the first opening 15A and the second opening 141
Under condition, the light L issued from light-emitting component 13 reaches light receiving element 14 via both the first opening 15A and the second opening 141,
Therefore, control unit 10 carries out being mounted on the case where being installed position identical operation with by new product toner Cartridge 9.Namely
Say, user without problem by new product toner Cartridge 9 as new product come using.
(2) feelings of the degree of light cannot be received at light receiving element 14 in the first opening 15A and 141 deviation of the second opening
Under condition, the light L issued from light-emitting component 13 does not reach light receiving element 14.Therefore, step of the control unit 10 in the flow chart of Figure 13
It is judged as NO in rapid S13, it is not that new product or toner Cartridge 9 are inclined from correct installation site that it may be toner Cartridge 9 that notice, which indicates,
The information (S15) of any situation from.Therefore, new product toner Cartridge 9 correctly can be reinstalled to peace by user
Install into position.
That is, image forming apparatus 1 according to the present embodiment, even if toner Cartridge 9 is new product and is located at the
Two middle positions are also judged as and do not install toner Cartridge 9, so as to inhibit by toner Cartridge 9 as new product come using.
