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： A cooling device includes a cooling member to cool a recording material. The cooling member includes a cooling surface member, a heat exchanging member, and a fastening member. The cooling surface member has a cooling surface to directly or indirectly contact the recording material and absorb heat of the recording material to cool the recording material. The heat exchanging member is directly or indirectly joined to the cooling surface member to radiate heat absorbed by the cooling surface member directly or indirectly via a radiation member. The fastening member fastens the cooling surface member and the heat exchanging member to retain a joined state in which the cooling surface member and the heat exchanging member are directly or indirectly joined to each other. The cooling surface member and the heat exchanging member are separable from the joined state to a separated state without damaging the fastening member.

摘要： A recording-material cooling device includes a first cooling member, a second cooling member, an approach-and-separation member, and a positioning member. The first cooling member is disposed at a first face side of a recording material to absorb heat of the recording material. The second cooling member is disposed at a second face side of the recording material to absorb heat of the recording material. The approach-and-separation member brings the first cooling member and the second cooling member close to and away from each other. The positioning member positions the first cooling member and the second cooling member relatively brought close to each other by the approach-and-separation member.

摘要： The developer conveyance amount on the upstream side of an agitation conveyance path in a developer conveyance direction becomes larger than the amount of developer to be transported from a recovery conveyance path to the agitation conveyance path, by making the developer conveyance amount on the upstream side of an agitating screw in the developer conveyance direction equal to or larger than the developer conveyance amount on the downstream side of a recovery screw in the developer conveyance direction. Accordingly, the bulk of the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from reaching the level where the recovered developer re-adheres to a developing roller, and further the developer existing on the downstream side of the recovery conveyance path in the developer conveyance direction can be prevented from re-adhering to the developing roller.
摘要翻译： 在显影剂输送方向上的搅拌输送路径的上游侧的显影剂输送量比通过将回收输送路径向搅拌输送路径输送的显影剂的量变大， 显影剂输送方向上的搅拌螺杆等于或大于在显影剂输送方向上的回收螺杆的下游侧的显影剂输送量。 因此，可以防止存在于回收输送路径的显影剂输送方向的下游侧的显影剂的大部分达到回收的显影剂重新附着到显影辊的水平，并且还可以使存在于下游侧的显影剂 可以防止显影剂传送方向上的恢复传送路径再次粘附到显影辊上。
