Note that the cross-sectional view shown in FIG. 4 represents a cross-section obtained by cutting the developing device along a plane perpendicular to the longitudinal direction shown in FIG. 4, the vertical direction is indicated by arrows as in FIG. 1. For example, the central axis of the developing roller 510 is below the central axis of the photoconductor 20. Further, in FIG. 4, the yellow developing device 54 is shown in a state where the yellow developing device 54 is located at a developing position facing the photoconductor 20.

  The developing device holding unit 50 includes a black developing device 51 containing black (K) toner, a magenta developing device 53 containing magenta (M) toner, a cyan developing device 52 containing cyan (C) toner, and yellow. (Y) Although the yellow developing unit 54 containing toner is provided, the configuration of each developing unit is the same, so the yellow developing unit 54 will be described below.

  The yellow developing device 54 includes a developing roller 510 as an example of a developer carrier, an upper seal 520, a toner container 530, a housing 540 as an example of a developer container, a toner supply roller 550, and an example of a layer thickness regulating member. The regulating blade 560 and the like are included.

  Thus, the developing roller 510, the regulating blade 560, the end seal 574, the upper seal 520, and the upper seal urging member 524 are assembled to the holder 526 to form one unit 563.

  As shown in FIGS. 7 to 9, the developing roller 510, the regulating blade 560, the upper seal 520, the end seal 574, the upper seal urging member 524, and the holder 526 in which these members are assembled, The unit 563 having the above is attached to the housing 540 through a housing seal 546. The housing seal 546 is sandwiched between the unit 563 and the housing 540 in a state where the unit 563 is attached to the housing 540.

  The housing seal 546 is provided along the opening 572 and exhibits a function of preventing the toner T from leaking from the opening 572. As shown in FIG. 10, the housing seal 546 is formed by hollowing out a central portion (rectangular portion) from a rectangular elastic body such as a malt plain, and includes a first seal portion 546a, a second seal portion 546b, And a third seal portion 546c.

  Here, the first seal portion 546 a is in contact with the upper seal support portion 527 and the housing 540 of the holder 526 and prevents the toner T from leaking between the upper seal support portion 527 and the housing 540. The second seal portion 546b is in contact with the rubber support portion 560b of the restriction blade 560 and the housing 540, and prevents the toner T from leaking between the rubber support portion 560b and the housing 540. The third seal portion 546c abuts on the end seal 574 and the housing 540 and exhibits a function of preventing leakage of the toner T from between the end seal 574 and the housing 540.

  The degree of compression of the second seal portion 546b in contact with the rubber support portion 560b of the regulating blade 560 and the rib 544r of the housing 540 is determined by the rubber support portion 560b and the surface 544f other than the rib 544r. The degree of compression of the contacted second seal portion 546b is greater.

  Further, as shown in FIG. 11, the housing seal 546 is fixed to only the housing 540 of the unit 563 and the housing 540 via a double-sided tape 580. The double-sided tape has a function as a displacement prevention unit for preventing displacement of the relative position between the housing 540 and the housing seal 546. As shown in FIG. 12, the double-sided tape 580 is provided only in a portion that does not face the blast portion 511a, specifically, only in a portion corresponding to the outside of the blast portion 511a in the longitudinal direction of the developing roller 510. ing.

=== Function of the slip prevention unit (double-sided tape 580) ===
As described above, in the present embodiment (first embodiment), the developing devices 51, 52, 53, and 54 are provided only in a portion that does not face the blast portion 511a, and the relative position between the housing 540 and the housing seal 546 is provided. A misalignment prevention unit (for example, double-sided tape 580) for preventing misalignment. This makes it possible to appropriately prevent the toner T from leaking from the opening 572 and improve the recyclability and reusability of the developing device. This will be described in detail below.

  First, a comparative example will be described. Here, a double-sided tape is affixed to the entire surface of the housing seal 546 according to the comparative example that faces the housing 540. The housing seal is sandwiched between the housing 540 and the unit 563, and the double-sided tape is bonded to the housing 540 even at a portion facing the blast portion 511a.

  In such a case, the housing seal 546 is less likely to be displaced with respect to the housing 540, and leakage of the toner T from the opening 572 can be prevented. However, the housing seal 546 is appropriately peeled from the housing 540 during recycling or the like. It is difficult. For example, when the housing seal 546 is peeled from the housing 540, a part of the double-sided tape remains in the housing or the housing seal 546 is broken, and it is difficult to peel the housing seal 546 appropriately. For this reason, the developing units 51, 52, 53, and 54 are not appropriately recycled or reused.

  On the other hand, in the first embodiment, a shift prevention portion is provided only in a portion that does not face the blast portion 511a, thereby preventing a relative position shift between the housing 540 and the housing seal 546.

  In such a case, since the positional deviation of the housing seal 546 with respect to the housing 540 is appropriately prevented, the leakage of the toner T from the opening 572 can be appropriately prevented. Further, since the shift preventing portion is provided only in a portion that does not face the blast portion 511a, the housing seal 546 can be easily peeled off from the housing 540. Therefore, the recyclability and reusability of the developing devices 51, 52, 53, and 54 can be improved.

  From the above, when the developing devices 51, 52, 53, and 54 have the above-described displacement prevention portion (for example, the double-sided tape 580), the housing seal 546 is prevented from being displaced with respect to the housing 540, while the housing seal 546 is Since the toner T is easily peeled from the housing 540, the leakage of the toner T from the opening 572 can be appropriately prevented, and the recyclability and reusability of the developing device can be improved.

  Further, when the slip prevention unit is provided only in a portion that does not face the blast part 511a, the slip prevention part may impair the function of the blast part 511a, that is, the function of carrying the toner T. It can be extinguished.

  In addition, when the developing devices 51, 52, 53, and 54 have the above-described misalignment prevention unit (for example, the double-sided tape 580), the assembling property of the developing device can be improved. This will be specifically described. When the housing seal 546 as a comparative example is used, it is necessary to prevent the generation of wrinkles when the housing seal 546 is attached. On the other hand, in the case where the developing device has a shift prevention portion (double-sided tape 580) only in a portion that does not face the blast portion 511a, such labor can be reduced. For this reason, when the developing device has a shift preventing portion, the housing seal 546 can be easily attached to the housing 540, so that the assembling property of the developing device can be improved.

  In the developing device according to the second embodiment, unlike the developing device according to the first embodiment, the double-sided tape 580 is not used between the unit 563 and the housing 540. Further, the configuration of the housing seal 646 as the second embodiment (hereinafter also simply referred to as “housing seal 646”) is different from the configuration of the housing seal 546 of the first embodiment.

  The housing seal 646 is provided along the opening 572 and prevents leakage of the toner T from the housing 540 (opening 572). As shown in FIGS. 13A and 13B, the housing seal 646 is applied to a surface facing the housing 540 with a slightly sticky adhesive (for example, an acrylic pressure sensitive adhesive). It has sex.

  In addition, said fine adhesion means the case where 90 degree direction peeling force (JIS Z 0237) at the time of making the housing seal 646 adhere to ABS resin is 5.0 (N / cm) or less, for example. In addition, the above slight adhesion may be a case where the 90-degree direction peeling force when the housing seal 646 is bonded to the SUS plate is 4.0 (N / cm) or less.

Thereby, since the surface is slightly sticky, it is possible to prevent the relative position between the housing 540 and the housing seal 546 from being shifted, and it is possible to appropriately prevent the leakage of the toner T from the housing 540. . Further, since the surface is slightly adhesive, the housing seal 546 can be easily peeled off from the housing 540, and the recyclability and reusability of the developing devices 51, 52, 53, and 54 can be improved.
Therefore, when the housing seal 646 is used, the leakage of the toner T from the housing 540 can be appropriately prevented, and the recycling and reuse of the developing devices 51, 52, 53, and 54 can be improved.
