    Abstract: An electrostatic latent image developing toner includes a plurality of toner particles each including a toner mother particle and an external additive attached to a surface of the toner mother particle. The external additive includes a plurality of resin particles each containing first temperature responsive polymer domains and second temperature responsive polymer domains. The second temperature responsive polymer domains have a lower critical solution temperature (LCST) higher than that of the first temperature responsive polymer domains.

    Abstract: A toner case includes a case main body, a rotator, a transmitter and a turner. The rotator is stored in the case main body and rotates around a rotation axis. The transmitter transmits rotation to the rotator. A part of the transmitter is exposed to an outside of the case main body. The turner is provided at an outside of the case main body in a rotation axis direction. The turner is turnable between a first posture and a second posture. At least a part of the turner is moved to an outside in the rotation axis direction as the turner turns from the first posture to the second posture. The transmitter moves from a first position to a second position which is arranged at an outside of the first position in the rotation axis direction as the turner turns from the first posture to the second posture.

    Abstract: A developing device includes a developing frame including a developing chamber, an accommodating chamber accommodating toner, and a partition wall provided with an opening connecting the developing chamber and the accommodating chamber. The developing device further includes an agitating member agitating the developer in the accommodating chamber, a shaft member including an attachment portion to which the agitating member is attached, and a conveying sheet conveying the toner. The conveying sheet includes a fixed portion fixed to the inner wall of the developing frame forming the accommodating chamber, and a displacement portion that is movable toward the opening by coming into contact with the agitating member. The rotation center of the shaft member is provided within an imaginary circle centered at the boundary point between the fixed portion and the displacement portion and passing through the distal end of the displacement portion.

    Abstract: A developer cartridge may include a gear configured to be movable between an engagement position in which the gear engages an auger or supply gear to provide toner from a toner container to a developing unit and a disengaged position in which the gear does not engage the auger or supply gear. The gear may be moved by a cam and/or cam gear from the engagement position to the disengaged position and vice versa. The cam gear may include toothless and toothed portions to allow the developer cartridge to maintain the movable gear in either the engagement position or the disengaged position. In some arrangements, an urging member such as a spring may bias the cam gear in a rotation direction, while a lever may provide a counteracting force when the movable gear is to be maintained in a particular position.

    Abstract: A developing cartridge has a casing accommodating toner therein; a developing roller rotatable about a first axis extending an axial direction; a cam electrically connected to the developing roller and rotatable about a second axis extending the axial direction from a first position to a second position, the cam being positioned at a third position distant from the casing by a first distance in the axial direction at the first position, and the cam being positioned at a fourth position distant from the casing by a second distance at the second position in the axial direction, the second distance being greater than the first distance; and a gear rotatable about the second axis, the gear engaging with the cam in a case where the cam is at the first position, and the gear disengaging from the cam in a case where the cam is at the second position.
