摘要： A powder container includes a discharge port configured to discharge powder stored in the powder container, a container shutter configured to open and close the discharge port, a first rotation portion configured to be engageable with an engagement portion of a removable component, an operation device configured to rotate the first rotation portion in conjunction with an operation of the operation device, and a contact portion included in the first rotation portion. The engagement portion opens and closes a cartridge shutter to open and close an inlet port of the removable component. A restriction member of the removable component is configured to restrict the rotation of the engagement portion. The contact portion contacts the restriction member to cancel the restriction member from restricting rotation of the engagement portion in conjunction with attachment of the powder container to the removable component.

摘要： A toner conveying device includes a conveying screw and a swinging member. The conveying screw includes a shaft portion and a screw portion spirally wound around the shaft portion. The swinging member has a substantially comb shape and swings between the shaft portion and the screw portion with rotation of the conveying screw, and includes a plurality of overhanging portions arranged side by side at intervals in an axial direction of the conveying screw and a plurality of tip portions, each one of which is bent at a predetermined angle from a free end side of a corresponding one of the plurality of overhanging portions in a direction away from the shaft portion. A width of each one of the plurality of tip portions gradually increases at least from a portion to contact the screw portion toward a free end side of each one of the plurality of tip portions.

摘要： An image forming apparatus includes a plurality of rotary members, a conveyance belt, an image forming device, and a switchback device. The conveyance belt is looped around the plurality of rotary members so as to circulate to intermittently feed a sheet in a sheet transport direction. The image forming device is disposed opposing the conveyance belt to form an image on the sheet fed by the conveyance belt. The switchback device is disposed downstream from the image forming device in the sheet transport direction to feed the sheet having passed the image forming device to a position downstream from the conveyance belt in the sheet transport direction and switch back the sheet. When the sheet is fed by the conveyance belt and the switchback device, a drive start timing of the switchback device is delayed from a drive start timing of the conveyance belt.

摘要： An opening and closing mechanism includes a movable member removably mounted relative to a main body of an apparatus, an opening and closing member having a cover portion, protrusions, and pivot shafts, and shaft position adjusters to change positions of the pivot shafts while the cover portion pivots between a closed position and an open position. The opening and closing member is arranged so that, on an imaginary plane perpendicular to a central axis of each pivot shaft on which each pivot shaft and the movable member are projected, a projected portion of each pivot shaft is positioned to interfere with a projected portion of the movable member when the cover portion is placed at the closed position, and the cover portion is positioned so as not to interfere with a trajectory of movement of the movable member while the cover portion pivots toward the open position.
