Abstract: A toner conveying apparatus conveying toner used for image forming includes a first conveying portion to convey the toner and having a first screw and a first conveying passage forming member that forms a first conveying space, and a second conveying portion to convey upward the toner and including a second screw and a second conveying passage forming member that forms a second conveying space. The second conveying passage forming member has a connecting port connected to the first conveying passage forming member. The second screw overlaps with the first screw viewed in a direction of a rotational axial line of the first rotation shaft. A cross-sectional area of the first conveying space orthogonal to the direction of the rotation axial line in a second region is smaller than the cross-sectional area of the first conveying space orthogonal to the direction of the rotational axial line in a first region.

Abstract: An image forming apparatus includes: a sheet feed unit that feeds a sheet to an image forming unit forming a toner image on the sheet; a fixing unit that fixes the toner image formed in the image forming unit to the sheet; and a control unit that controls the sheet feed unit, when starting duplex image formation for forming both sides of the sheet after an one-side image formation, the control unit retards a timing to cause the sheet feed unit to start the sheet feed operation as the number of sheet with an image formed on one side thereof in the one-side image formation is greater.

Abstract: An image forming apparatus includes a cartridge, a first door, and a second door. The first door is movable between a first closed position and a first open position to permit dismounting the cartridge from the main. The second door is movable, independently of the first door, between a second closed position for closing the main assembly and a second opened position for uncovering the first door and for opening the main assembly. The second door is provided with a recess. When the first door is in the first open position, the recess of the second door is capable of accommodating at least a part of the first door. The cartridge is capable of being inserted into the main assembly while sliding on the second door and then on the first door.

Abstract: Provided is a one-way clutch in which a rotating direction of a first rotating member with respect to a second rotating member is switched. The first rotating member includes a recessed portion that receives a planetary gear and, in an outer circumferential portion thereof, an engaging portion that engages with the planetary gear, whereby relative rotation of the planetary gear and the first and second rotating members is switched to rotatable and unrotatable. When the first rotating member is relatively rotating with respect to the second rotating member, the planetary gear meshes with an internal gear of the second rotating member, and the position of the planetary gear is thereby restricted.

Abstract: A feeding apparatus includes a stacking member provided to a feeding cassette, a feeding member, a contact portion provided on a regulating member provided on the feeding cassette, a movement unit, and a switching unit. The movement unit raises the feeding member when the feeding cassette is pulled out and lowers the feeding member when the feeding cassette is inserted. The switching unit switches a positional relationship between the feeding and stacking member. After the feeding member is lowered and before the feeding member performs a sheet feeding operation, the switching unit switches the relationship to the second positional relationship from the first. When a stacked sheet amount is equal to or more than a predetermined amount, the contact portion is disposed in contact with the stacked sheets and when the amount is smaller than the predetermined amount, the contact portion is disposed not in contact with the stacked sheets.

Abstract: A toner conveying apparatus includes: a first conveying portion to convey the toner, the first conveying portion having a first screw that is rotatable, and a first conveying passage forming member that forms a first conveying space so as to surround the first screw; and a second conveying portion to convey upward the toner from the first conveying portion, the second conveying portion having a second screw that is rotatable, and a second conveying passage forming member that forms a second conveying space so as to surround the second screw and that includes a connecting portion. The first conveying space includes a first region and a second region that is closer to the connecting portion than the first region is, and a cross-sectional area of the first conveying space is smaller in the second region than in the first region.

Abstract: An image forming apparatus includes a feeder unit, a separating unit, a conveying unit disposed downstream of the separating unit in a sheet feeding direction, an image forming unit disposed downstream of the conveying unit in the sheet feeding direction, a drive unit, and a control unit. The feeder unit feeds a sheet. The separating unit separates sheets fed by the feeder unit one by one. The conveying unit conveys the sheet. The image forming unit forms, while the sheet is being conveyed, an image on the sheet. The drive unit drives the conveying unit. The control unit controls the drive unit. After the conveyed sheet reaches the image forming unit, the control unit reduces a conveyance speed of the sheet conveyed by the conveying unit.
