摘要： The invention provides a developer supply device, a developer container, a developer and an image forming apparatus such that the developer is discharged stably from the developer container with a stable toner concentration in the developer, without damaging the developer, and in a relatively simple and small-size device having a relatively high degree of freedom as regards layout. The developer supply device comprises a partially or wholly deformable developer container and a pump for suctioning the developer held in the developer container, together with a gas, and for discharging the developer towards a developing unit. The toner comprises an additive formed so as to have a volume average particle size of 50 to 500 nm. The carrier is formed so as to have a weight average particle size of 20 to 60 μm. The developer is formed so that the carrier concentration thereof is 1 to 30 wt %.

摘要： A developing-agent container contains a developing agent to be supplied to a developing unit. The developing agent contains toner and carrier. The developing-agent container is filled with the developing agent with the toner and the carrier evenly distributed in a highly air-containing state. After filling the developing-agent container with the developing agent, an external force is applied on at least one of the toner and the carrier in the toner container so that a difference in forces per unit volume of the toner and the carrier due to gravity becomes small.

摘要： An image forming apparatus including a conveyance unit to convey a transfer medium, a first image forming unit to form a monochrome image transferred at a first transfer position onto the transfer medium, and a second image forming unit disposed downstream from the first image forming unit in a direction of conveyance of the transfer medium, including an intermediate transfer body to form a multi-colored toner image on the intermediate transfer body. The multi-colored toner image is transferred onto the transfer medium at a second transfer position. The conveyance unit is separated from the intermediate transfer body at the second transfer position in a monochrome mode to form the monochrome image using only the first image forming unit, and contacts the intermediate transfer body at the second transfer position in a full-color mode to form a full-color image using both the first and second image forming units.

摘要： An image forming apparatus of the present invention includes a toner content controller configured to set the target value of a toner content sensor for determining, after a developing unit has been driven for a preselected period of time since the detection of the replacement of a toner cartridge, that a toner-end recovery operation has been completed. Subsequently, every time a preselected toner replenishing cycle is executed, the toner content controller determines whether or not the output voltage Vt of the toner content sensor has decreased below Vt10-0.1 V and determines, if the answer of this decision is positive, that a toner-end recovery operation has completed.
