摘要： A cleaning device includes a toner storing container that stores a collected toner, a conveyance screw that conveys toner in the toner storing container, and a toner crushing member that crushes the toner accumulated in the toner storing container. The toner crushing member is formed so as to include: a supporting portion being attached above a rotation axis of the conveyance screw; and a plurality of elastic pieces each extending from the supporting portion toward the conveyance screw and being swung by a fin that rotates in association with the rotation of the conveyance screw. Each of the elastic pieces is formed with a raised portion rising toward the seal member, so that the elastic pieces come in contact with the seal member.

摘要： An image forming apparatus includes a waste toner case, an optical sensor, a cover and a shading member. The waste toner case is attachably/detachably provided in an apparatus main body via an opening part. The waste toner case collects a waste toner ejected from an image forming part forming an image by a toner. The optical sensor detects whether or not the waste toner case is filled with the waste toner. The cover closes the opening part of the apparatus main body. The shading member is arranged between the cover and optical sensor. The shading member covers the optical sensor in a state where the cover is closed.

摘要： An image forming apparatus includes an image carrier, a removal roller, a collection roller, a housing, a screw, and a seal. The removal roller rotates while in contact with the intermediate transfer belt and removes residual toner from the intermediate transfer belt. The collection roller rotates while in contact with the removal roller so as to collect, from the removal roller by electrostatic force, waste toner that is the residual toner removed by the removal roller. The housing has an upper opening for receiving the waste toner collected by the collection roller and stores the waste toner. The screw conveys the waste toner stored in the housing. The seal comes into contact with the collection roller and closes a gap between the collection roller and the housing at the upper opening.

摘要： An image forming apparatus includes a housing, a photosensitive drum, a cleaning member, a driving transmission portion, and a movement mechanism. The photosensitive drum is rotatably supported by the housing about a first shaft portion. The driving transmission portion transmits a rotation driving force to the photosensitive drum. The movement mechanism reciprocates the photosensitive drum in an axial direction. The movement mechanism includes a first rotation gear, a second rotation gear, a first intermediate gear, and a second intermediate gear. The first rotation gear integrally rotates with the photosensitive drum. The second rotation gear has teeth different in number from teeth of the first rotation gear and rotates with a predetermined speed difference relative to the first rotation gear. The first and second intermediate gears are a pair of rotation gears rotatable about a second shaft portion parallel to the first shaft portion.

摘要： 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).
