Abstract: A charging device (51) includes a charging roller (65), a supporting section (71), a guide (73), a first biasing section (75), and a second biasing section (90). The charging roller (65) charges an image bearing member (50). The supporting section (71) supports the charging roller (65) such that the charging roller (65) is rotatable. The guide (73) guides the supporting section (71) in a first direction (D1). The first biasing section (75) biases the supporting section (71) in the first direction (D1) to press the charging roller (65) against the image bearing member (50). The second biasing section (90) biases the supporting section (71 toward the guide (73).

Abstract: A drive transmission mechanism includes a drive transmission gear, an output-side coupling, and a first drive transmission member. The drive transmission gear includes a cylindrical boss formed at the rotation center, a circular rim concentric with the boss, and a web coupling the boss with the rim. The output-side coupling outputs a driving force of the drive transmission gear to a driven member. The first drive transmission member has higher rigidity than the drive transmission gear, and transmits the driving force of the drive transmission gear to the output-side coupling by rotating together with the drive transmission gear. The output-side coupling incline in an arbitrary direction relative to the rotation axis of the first drive transmission member, and the driving force from the drive transmission gear is transmitted to the outer circumferential rim of the first drive transmission member.

Abstract: A developing device includes: a developing roller; a toner supplying roller; a regulation blade; a casing; a film member; a bias member; and a protrusion. The casing includes an inner wall portion which opposes the developing roller between the blade roller and the image carrier. The film member is flexible, disposed to oppose an upper surface of the inner wall portion over a predetermined gap and vibratile in a direction to approach or leave the inner wall portion. The bias member is connected to at least one end in a longitudinal direction of the film member and gives tension to the film member. The protrusion is disposed on a gear composing a group of drive gears of the developing roller or the toner supplying roller and intermittently contacts an end edge of the film member thanks to rotation of the gear to vibrate the film member.

Abstract translation: 显影装置包括：显影辊; 调色剂供应辊; 调节刀片 套管 电影会员 偏置构件; 和突起。 壳体包括与刮板辊和图像载体之间的显影辊相对的内壁部分。 薄膜构件是柔性的，设置成与预定间隙相对的内壁部分的上表面，并且在接近或离开内壁部分的方向上是振动的。 偏置构件连接到薄膜构件的纵向方向上的至少一个端部，并且对薄膜构件施加张力。 突起被设置在构成显影辊或调色剂供应辊的一组驱动齿轮的齿轮上，并且由于齿轮的旋转而间隔地接触薄膜构件的端边缘以使薄膜构件振动。
