<Description of Configuration of Cleaning Device 17>
FIG. 2 is a diagram showing the configuration of the cleaning device 17.
As illustrated, the cleaning device 17 includes a housing 171, a cleaning blade 172, a base 173, a screw 174, and a deformation member 175.

The housing 171 has a rectangular parallelepiped shape with one open surface, and accommodates the cleaning blade 172, the base 173, the screw 174, and the deformation member 175 inside.
The cleaning blade 172 as an example of the cleaning member includes a rubber 172A and a holder 172B provided with a longitudinal direction (main scanning direction) extending along the axial direction of the photosensitive drum 11.

  The rubber 172A is a member made of a rubber material such as urethane rubber and having a rectangular parallelepiped shape. Then, the rubber 172A comes into contact with the photosensitive drum 11 that rotates on the upper surface 172Aa, so that the deposits remaining on the surface of the photosensitive drum 11 after transferring the toner image to the paper are dammed up, and the deposits are damped. 11 to remove. The deposit removed by the rubber 172A is accommodated in the housing 171. The holder 172B is made of a metal such as stainless steel, and extends upward from the support portion 172Ba that supports the bottom surface 172Ab of the rubber 172A from below, and on the far side of the support portion 172Ba from the photosensitive drum 11. It consists of extending | stretching part 172Bb provided. The support portion 172Ba fixes the rubber 172A with an adhesive.

  The base 173 as an example of the first support member is fixed on the housing 171 with screws or the like (not shown), and is made of a resin having a lower elastic modulus than the holder 172B. The base 173 faces the photosensitive drum 11 via the cleaning blade 172, and one end and the other end in the longitudinal direction of the support portion 172Ba of the holder 172B are arranged from below the support portion 172Ba. Support each one.

  The screw 174 is a male screw and is provided so as to penetrate the holder 172B and reach the base 173. The base 173 is provided with a female screw, and the screw 174 screws one end and the other end in the longitudinal direction of the support portion 172Ba of the holder 172B from above the support portion 172Ba. Therefore, the holder 172B is fixed to the base 173 with the screw 174, and the distance between the cleaning blade 172 and the photosensitive drum 11 is kept constant.

  The deformable member 175 as an example of the second support member is opposed to the photosensitive drum 11 via the cleaning blade 172, and the support 172Ba is moved downward along with the base 173 at the center in the longitudinal direction of the support 172Ba of the holder 172B. Support from. Details of the deformable member 175 will be described later.

<Description of Deflection Generated in Cleaning Blade 172>
Next, the deflection generated in the cleaning blade 172 in the conventionally used cleaning device 17 will be described.
FIG. 3 shows a conventional configuration for supporting the cleaning blade 172. In addition, the same code | symbol is used about the structure similar to this embodiment.
As shown in the figure, also in the cleaning device 17 used conventionally, both end portions in the longitudinal direction of the support portion 172Ba of the holder 172B are sandwiched between the base 173 and the screw 174, respectively, as in the present embodiment. Fix it.

  As described above, the upper surface 172Aa of the rubber 172A of the cleaning blade 172 is pressed against the rotating photosensitive drum 11 in order to remove the deposits remaining on the photosensitive drum 11 after the toner image is transferred to the paper. Therefore, the rubber 172A receives a pressing force from the pressed photosensitive drum 11 in the direction of arrow A (downward in the figure). The holder 172B is also pressed against the photosensitive drum 11 via the rubber 172A, and therefore receives a pressing force from the photosensitive drum 11 in the direction of arrow A in the figure.

  Here, the support portion 172Ba of the holder 172B is moved from the base 173 facing the photosensitive drum 11 via the holder 172B in the direction of arrow B (upward in the figure) opposite to the direction of arrow A in the figure. A reaction force against the pressing force from the photosensitive drum 11 is received. Thus, the cleaning device 17 prevents the cleaning blade 172 that receives the pressing force from the photosensitive drum 11 from moving.

However, in the cleaning device 17 conventionally used, the holder 172B is supported between one end and the other end in the longitudinal direction of the support portion 172Ba of the holder 172B supported by the base 173 and the screw 174. Did not exist.
Therefore, the support portion 172Ba of the holder 172B has a direction indicated by an arrow C in the drawing due to the pressing force of the photosensitive drum 11 as shown by a broken line portion in the drawing (the same direction as the arrow A direction in the drawing). In particular, a large deflection occurred at the center in the longitudinal direction of the support portion 172Ba of the holder 172B. Here, the central part means the center and its periphery.

  Further, at the center in the longitudinal direction of the holder 172B, the support portion 172Ba of the holder 172B is bent, so that the distance between the support portion 172Ba and the photosensitive drum 11 is increased. As a result, if the distance between the rubber 172A fixed on the support portion 172Ba and the photosensitive drum 11 is also increased, poor contact occurs between the photosensitive drum 11 and the rubber 172A. As a result, there may occur a poor cleaning state in which the rubber 172A cannot remove the deposits remaining on the surface of the photosensitive drum 11.

  Here, in order to suppress the bending which arises in the longitudinal direction center part of support part 172Ba of holder 172B, it is possible to support the longitudinal direction center part of support part 172Ba from the downward direction. However, when the support portion 172Ba of the holder 172B is supported using a new member, if the accuracy of the size of the member varies, the holder 172B and the photosensitive drum that have been adjusted using the base 173 and the screw 174 are used. The distance between 11 can vary. That is, when the height of the new member is lower than the base 173, the support portion 172Ba of the holder 172B cannot be sufficiently supported, and the deflection generated in the holder 172B due to the pressing force from the photosensitive drum 11 is not possible. Can not be suppressed.

  On the other hand, when the height of the new member is higher than that of the base 173, the holder 172B receives a reaction force larger than that received from the base 173 from the supported new member. In this case, a deflection in the direction opposite to the arrow A direction (upward in the figure) in the longitudinal direction of the support part 172Ba of the holder 172B occurs. For this reason, the pressing force received from the photosensitive drum 11 is particularly strong at the central portion in the longitudinal direction of the rubber 172A, and the rubber 172A may be significantly consumed accordingly.

  Therefore, conventionally, a sufficiently thick holder 172B has been adopted to suppress the deflection generated in the holder 172B. However, in this case, there has been a problem that the cleaning device 17 cannot be manufactured at low cost.

<Description of Deformation Member 175>
Therefore, in the present embodiment, the deformation member 175 described above is provided so as to support the support portion 172Ba from below at the center portion in the longitudinal direction of the support portion 172Ba of the holder 172B.
FIG. 4 shows the configuration of the deformable member 175.
As shown in the drawing, the deformable member 175 has a shape made of a triangular pyramid, and is made of a resin having a lower elastic modulus than the holder 172B, like the base 173.

  Further, the deformable member 175 is higher than the base 173 and becomes thinner as it approaches the holder 172B, and the portion of the holder 172B that contacts the support portion 172Ba forms a vertex. Therefore, even when the base 173 and the deformable member 175 that support the support portion 172Ba of the holder 172B receive the same pressing force from the holder 172B, the deformable member 175 is more easily removed from the holder 172B than the base 173. It easily deforms due to the pressing force it receives, and the amount of deformation is larger. Here, a portion of the deformable member 175 that is in contact with the support portion 172Ba of the holder 172B and forms a vertex is the deformable portion 175B. The deformation portion 175B of the deformation member 175 is configured to be thinner than the holder 172B.

FIG. 5 is a front view showing a configuration in which the cleaning blade 172 is supported using the deformable member 175 shown in FIG.
As shown in the drawing, the deformable member 175 elastically supports the support portion 172Ba of the holder 172B at the center in the longitudinal direction of the holder 172B. Here, the holder 172B is not fixed to the deformable member 175. That is, the deformable member 175 supports the cleaning blade 172 by contacting the support portion 172Ba of the holder 172B.

  The support portion 172Ba of the holder 172B is moved from the deformable member 175 facing the photosensitive drum 11 via the holder 172B in the direction of arrow D (upward in the figure) opposite to the direction of arrow A in the figure. A reaction force against the pressing force from the photosensitive drum 11 is received. Thereby, even if the pressing force is received from the photosensitive drum 11, the holder 172B is less likely to bend. The distance between the cleaning blade 172 and the photosensitive drum 11 is kept constant, so that the cleaning blade 172 to the photosensitive drum 11 caused by poor contact between the photosensitive drum 11 and the rubber 172A is generated. Cleaning failure is suppressed.

  Further, as shown in the figure, the deforming portion 175B of the deforming member 175 that is a portion that contacts the holder 172B is different from the base 173, and when it contacts the holder 172B, it is in the direction of arrow E (the same as the direction of arrow A in the drawing). Direction and downward in the figure). Therefore, the distance between the holder 172B and the photosensitive drum 11 does not change depending on the presence of the deformation member 175. Thereby, in the holder 172B, the distance between the cleaning blade 172 and the photosensitive drum 11 caused by the support portion 172Ba being supported at the longitudinal center of the support portion 172Ba is suppressed.

<Description of Other Configuration Examples of Deformation Member 175>
In the present embodiment, the longitudinal central portion of the support portion 172Ba of the holder 172B of the cleaning blade 172 is supported using the deformable member 175, so that the deflection of the longitudinal central portion of the support portion 172Ba is suppressed and the cleaning blade It has been described that the displacement of the distance between the 172 and the photosensitive drum 11 is prevented. Here, the deformation member 175 is not limited to that shown in FIGS.

FIG. 6 is a diagram illustrating another configuration example of the deformable member 175.
In the configuration example shown in FIG. 6, the deformation member 175 includes a pedestal portion 175A having a rectangular parallelepiped shape and a deformation portion 175B extending upward from a part of the upper surface of the pedestal portion 175A. Here, the deforming portion 175B is configured to be thinner than the pedestal portion 175A.

FIG. 7 is a front view showing a configuration in which the cleaning blade 172 is supported using the deformable member 175 shown in FIG. In addition, the same code | symbol is used about the structure similar to the structure shown in FIG.
As shown in the figure, the deformable member 175 supports the support portion 172Ba of the holder 172B at the longitudinal center of the holder 172B, so that the support portion 172Ba is separated from the deformable member 175 in the direction indicated by the arrow D (upward in the figure). ) Receives a reaction force against the pressing force from the photosensitive drum 11. Further, when the deformable member 175 supports the support portion 172Ba, the deformable portion 175B of the deformable member 175 is deformed so that the tip portion that is a portion in contact with the support portion 172Ba is bent, but lower than the tip portion. The root part at is not deformed. Accordingly, even when the pressing force is received from the photosensitive drum 11, the holder 172B is less likely to bend, and the cleaning blade 172 and the photosensitive member are generated when the support portion 172Ba is supported at the longitudinal center of the support portion 172Ba. The distance from the drum 11 is suppressed from shifting. Note that the base 173 configured to be thicker than the deforming portion 175B hardly deforms.

FIG. 8 is a view showing another configuration example of the deformable member 175. FIG. 8A is a perspective view of another configuration example, and FIG. 8B is a front view of the other configuration example.
In the configuration example shown in FIG. 8, the deformable member 175 has the same shape as the pedestal 175A having a rectangular parallelepiped shape, the deformed portion 175B extending upward from a part of the upper surface of the pedestal 175A, and the pedestal 175A. The stacking unit 175C is stacked on the deforming unit 175B. Here, the deforming portion 175B is configured to be thinner than the pedestal portion 175A and the stacking portion 175C.

FIG. 9 is a front view showing a configuration in which the cleaning blade 172 is supported using the deformable member 175 shown in FIG. Again, the same reference numerals are used for the same components as those shown in FIG.
As shown in the figure, the deformable member 175 supports the support portion 172Ba of the holder 172B at the longitudinal center of the holder 172B, so that the support portion 172Ba is separated from the deformable member 175 in the direction indicated by the arrow D (upward in the figure). ) Receives a reaction force against the pressing force from the photosensitive drum 11.

  Further, when the deformable member 175 supports the support portion 172Ba, the deformable portion 175B positioned between the pedestal portion 175A and the stacking portion 175C is inclined in an oblique direction with respect to the arrow D direction in the drawing. Along with this, the stacking portion 175C is shifted to either the front, rear, left or right with respect to the pedestal portion 175A, the pedestal portion 175A and the stacking portion 175C come close to each other, and the deformable member 175 is deformed so that the height is reduced. Accordingly, even when the pressing force is received from the photosensitive drum 11, the holder 172B is less likely to bend, and the cleaning blade 172 and the photosensitive member are generated when the support portion 172Ba is supported at the longitudinal center of the support portion 172Ba. The distance from the drum 11 is suppressed from shifting. Note that the base 173 configured to be thicker than the deforming portion 175B hardly deforms.
