Abstract
A developing device includes: a case in which a hollow transporting path is formed; a transporting member configured to transport a developer in the transporting path; a support portion fixed to an end portion of the case by a fastening member to support the transporting member at an end portion of the transporting path; and a cooling unit fixed by being sandwiched between the support portion and the case.
Claims16
A developing device comprising:
- a case in which a hollow transporting path is formed;
- a transporting member configured to transport a developer in the transporting path;
- a support portion fixed to an end portion of the case by a fastening member to support the transporting member at an end portion of the transporting path;
- and
- a cooling unit fixed by being sandwiched between the support portion and the case, wherein the cooling unit is fixed by being sandwiched between the support portion and the transporting path in a state of being pressed against an inner surface, facing a transporting direction of the developer, of a recessed portion provided along the transporting path inside the case.
2 more elements
A developing device comprising:
- a transporting path that is hollow and through which a developer is transported, wherein:
- a part of a surface constituting the transporting path is formed by a cooling unit formed of a material having a heat conductivity higher than a heat conductivity of another part of the surface,
- the transporting path is covered with a housing,
- a portion of the housing located outside the cooling unit is provided with an opening portion through which the cooling unit faces an outside of the housing,
- the housing includes:
- an elongated body side housing and
- an end portion side housing positioned at one end portion of the body side housing, and
- the opening portion is provided on the end portion side housing.
5 more elements
A developing device comprising:
- a case having a first transporting path and a second transporting path adjacent to the first transporting path;
- a first transporting member and a second transporting member configured to transport a developer so as to circulate the developer between the first transporting path and the second transporting path via a communication hole;
- and
- a cooling unit disposed at a position adjacent to the communication hole in the case and formed of a material having a heat conductivity higher than a heat conductivity of the case, wherein:
- the first transporting member is formed so as to supply the developer to surroundings,
- the second transporting member is formed so as to stir the developer, and
- the cooling unit is disposed in the second transporting path.
