ABSTRACT:
A developing device according to the present invention includes a developer storing section storing a developer, a stirring member disposed in the developer storing section and transporting the developer while stirring the developer, a developer carrier receiving the developer from the developer storing section and carrying the developer, a developer regulating member regulating the amount of the developer received by the developer carrier from the developer storing section, and a heat-dissipating member disposed at a position in contact with the developer and capable of dissipating heat of the developer. The heat-dissipating member has a surface in contact with the developer and the contact surface of the heat-dissipating member has an arithmetic surface roughness Ra1that is set to be equal to or less than ⅓ of the volume average particle size of toner particles contained in the developer.
