摘要： A developing apparatus includes a mode in which a control of differentiating a relationship between a rotational speed (Vsc) of a conveying portion (31 and 32) and a rotational speed (Vsl) of a developer carrier (6) in forming no image from that in forming an image is executed. In the mode, the developing apparatus executes at least one of controls of restraining a trouble otherwise caused by the control of differentiating the relationship such as a control of decreasing a ratio of rotational speeds (Vsc/Vsl) as compared to the ratio of rotational speeds in forming the image, a control of circulating the developer between first and second chambers by driving the conveying portion (31 and 32) and the developer carrier (6) at rotational speeds lower than those in forming the image.

摘要： A toner cartridge includes a toner container to store toner and two rotary agitation members to rotate to agitate toner in the toner container. The toner container has two arc-shaped portions adjacent to each other at an inner bottom wall of the toner container. The two rotary agitation members has edges to rotate along the two arc-shaped portions with rotation phases thereof shifted from each other. The two rotary agitation members are placed with rotation trajectories thereof partially overlapping each other.

摘要： A developer cartridge assembled to a developing device defining therein a developing chamber. The developer cartridge includes a first accommodating portion, and a first agitator. The first accommodating portion accommodates therein a developing agent and is positioned beside the developing device. The first accommodating portion includes a first wall part neighboring the developing device. The first wall part is formed with a first through-hole and a second through-hole. The first through-hole is open diagonally downward from the first accommodating portion to the developing device. The second through-hole is open diagonally upward from the first accommodating portion to the developing device. The first through-hole and the second through-hole allow communication between an interior of the first accommodating portion and the developing chamber. The first agitator is rotatably disposed in the first accommodating portion and in sliding contact with the first wall part in a vertical direction.
