As shown in Figure 1 and Figure 5, under the state of Delevoping cartridge installation portion 70 that Delevoping cartridge 3 is installed on drum frame 4, the diapire 36 of Delevoping cartridge 3 and drum frame 4 are in the vertical direction toward each other.And multiple transmission ribs 50 of Delevoping cartridge 3 expose from the second opening 58 of drum box 2.And as shown in Figure 6, when observing from above-below direction, each of multiple transmission ribs 50 of Delevoping cartridge 3 is overlapping with each of multiple protuberances 64 of the first jog 61, and overlapping with each of multiple recesses 67 of the second jog 62.In other words, when observing from above-below direction, multiple transmission ribs 50 of Delevoping cartridge 3 are configured between multiple protuberances 68 of the second jog 62 respectively.

6. the relative configuration of handle box and main body side rib

Under the state that handle box 1 is arranged on main body cover 21, as shown in Figure 7, multiple main body side ribs 80 are configured in the below of handle box 1.Specifically, as shown in Figure 6 and Figure 7, multiple main body side rib 80 each in the vertical direction with multiple transmission ribs 50 of Delevoping cartridge 3 each toward each other.And as shown in Figure 7, each of multiple main body side rib 80 is overlapping with each of multiple recesses 67 of the second jog 62 of Delevoping cartridge 3 when above-below direction projects.

7. air is towards the flowing of handle box

When starting image and form action in printer 20, paper P moves along the lower surface of the rearward end of handle box 1 towards rear.Then, paper P, via the medial movement of the second opening 58 to handle box 1 of rousing box 2, after by the below of transfer roll 6, moves to the outside of handle box 1 via the first opening 75.After this, move towards fixation unit 23.

Now, as shown in Figure 6, by the second opening 58, air flows into the inner side of handle box 1, or the air in handle box 1 is discharged laterally.Specifically, with by multiple recesses 63 of the first jog 61 each, the mode in each and region between the first jog 61 and the second jog 62 of multiple recesses 67 of the second jog 62, air flows into the inner side of handle box 1, or the air in handle box 1 is discharged laterally.

And, can utilize towards the surrounding cooling of the air of developer roll 12 by developer roll 12.

In addition, about the air flowed into by the first jog 61, second jog 62 in handle box 1, specifically, after each of multiple recesses 63 of the first jog 61 is passed through in the outside of handle box 1, by multiple recesses 67 of the second jog 62 each and move to air in handle box 1 along multiple main body side rib 80 each and move, and along and the direction that intersects of fore-and-aft direction flow.

Specifically, in the longitudinal direction, multiple recess 63 each with adjacent to each multiple protuberances 68 of multiple recess 67 each toward each other, in other words, in the lateral direction, each of multiple protuberance 64 is configured in each the different position from multiple protuberance 68 respectively.Therefore, intersect from each each direction towards multiple recess 67 of multiple recess 63 with fore-and-aft direction.That is, from each of multiple recess 63 flow into and via multiple recesses 67 of the second jog 62 each and to the air of movement in handle box 1 flowing along multiple main body side rib 80 each and move, and flow in edge and the direction that intersects of fore-and-aft direction.

Then, the air in inflow handle box 1 is in each mode of the multiple transmission ribs 50 along Delevoping cartridge 3, and after the lower surface rearward movement of the rearward end of the diapire 36 of Delevoping cartridge 3, the below towards transfer roll 6 is moved.

8. action effect

(1) according to this drum box 2, as shown in Figure 6, in drum box 2, the first jog 61 is configured in front side relative to the second opening 58, and the second jog 62 is configured in rear side relative to the second opening 58.And the first jog 61 possesses multiple recess 63 and multiple protuberance 64, second jog 62 possesses multiple recess 67 and multiple protuberance 68.

Therefore, it is possible to make the area of the second opening 58 increase by multiple recess 63 and multiple recess 67.

Consequently, the amount of the air by the second opening 58 can be increased, can increase towards the amount of the air of developer roll 12.

Therefore, it is possible to successfully cool developer roll 12 around.

(2) according to this Delevoping cartridge 2, as shown in Figure 6, multiple recesses 63 of the first jog 61 each in the longitudinal direction with multiple protuberances 68 of the second jog 62 each toward each other.Multiple recesses 67 of the second jog 62 each in the longitudinal direction with multiple recesses 63 of the first jog 61 each toward each other.In other words, in the lateral direction, each of multiple protuberance 64 is configured in each the different position from multiple protuberance 68.

Therefore, intersect from each each direction towards multiple recesses 67 of the second jog 62 of multiple recesses 63 of the first jog 61 with fore-and-aft direction.

Consequently, the multiple recesses 63 from the first jog 61 each leaked-in air via multiple recesses 67 of the second jog 62 each and when flowing into the inner side of handle box 1, the side that air is intersecting with fore-and-aft direction moves up.

Therefore, it is possible to make air along the more region flowing of developing frame 11.

Therefore, it is possible to more successfully cool developer roll 12 around.

(3) and, according to this handle box 1, as shown in Figure 1, multiple transmission rib 50 is overlapping with developer roll 12 when projecting along the vertical direction.

Therefore, the air along the movement of multiple transmission rib 50 moves near developer roll 12.

Consequently, developer roll 12 can more successfully be cooled around.

(4) and, according to this handle box 1, as shown in Figure 6, under the state that Delevoping cartridge 3 is installed on bulging box 2, multiple transmission rib 50 is overlapping with multiple protuberances 64 of the first jog 61 when projecting along the vertical direction.

Therefore, it is possible to each making from the first jog 61 leaked-in air along multiple transmission rib 50 successfully moves.

Consequently, developer roll 12 can more effectively be cooled around.

(5) and, according to this printer 20, as shown in Figure 6, under the state that handle box 1 is arranged on main body cover 21, multiple main body side ribs 80 of main body cover 21 each in the vertical direction with multiple transmission ribs 50 of Delevoping cartridge 3 each toward each other.

Therefore, utilize each of multiple main body side rib 80, air can be made successfully to flow into towards each of multiple transmission rib 50.

Consequently, developer roll 12 can more successfully be cooled around.

And, can utilize multiple main body side rib 80 each and successfully transmit recording medium.

(6) and, according to this printer 20, as shown in Figure 7, under the state that handle box 1 is arranged on main body cover 21, overlapping with each of multiple recesses 67 of the second jog 62 of Delevoping cartridge 3 when multiple main body side ribs 80 of main body cover 21 project on along the vertical direction.

Therefore, it is possible to utilize multiple main body side rib 80 each and air is successfully flowed into towards each of multiple recess 67.

Therefore, it is possible to more successfully cool developer roll 12 around.
