摘要： A liquid type cooling device, which is incorporated in an image forming apparatus, includes a heat receiving part including a heat receiving unit to transport heat from a cooling target to a coolant and a heat releasing part including a heat releasing unit, a cooling fan, and an air flowing space. The heat releasing unit has a coolant flowing path and an air flowing path through which air passes and conducts heat exchange with the coolant. The air flowing space has an air inlet port and an air outlet port. When the air flowing path has an upstream region and a downstream region along a coolant flowing direction of the coolant flowing path, air at high temperature flows into the upstream region of the air flowing path. Alternatively, the heat releasing unit may have a coolant inlet port, a coolant outlet port, and the air flowing path.

摘要： An image forming apparatus includes a cooling conveyor to cool a recording material having an image fixed by heat while sandwiching and conveying the recording material. The cooling conveyor includes a conveyance belt, a cooling member, and a cooling unit. The conveyance belt sandwiches and conveys the recording material. The cooling member absorbs heat of the recording material via the conveyance belt. The cooling unit maintains the cooling member at low temperature. The cooling conveyor performs control of stopping the cooling unit in a standby state of the image forming apparatus, activating the cooling unit and performing a preliminary cooling operation to decrease temperature of the cooling member after a shift from the standby state to image forming operation, and then bringing the recording material into contact with the conveyance belt.

摘要： A developing device, process cartridge, and image forming apparatus, have transport members with screw and shaft portions, transporting developer within the device in a longitudinal direction of a circulation path. A supply supplies new carrier to the device. A discharge aperture in a transport path wall of one transport member discharges developer outside the circulation path, when a surface of the developer transported by the one transport member exceeds a predetermined height. A bias path aperture in the transport path wall upstream of the discharge aperture has a bottom at a higher level than a bottom of the discharge aperture, and diverts developer at a level higher than the bottom of the discharge aperture to another transport member. An area in the longitudinal direction of the one transport member has no screw portion, and the discharge aperture is disposed opposite the area and has a length smaller than the area.
