A fixing device includes: a fixing roll member; a support roll member; a fixing belt member rotated while being mounted on and tensioned by the fixing roll member and the support roll member; a roll heating unit that heats the fixing roll member; a belt heating unit that heats the fixing belt member; a pressing member that is in press contact with a portion of the fixing roll member, around which the fixing belt member is wound, to form a nip portion; and a temperature controlling device that controls and drives the roll heating unit and the belt heating unit. The temperature controlling device controls the fixing roll member and the fixing belt member to be different temperatures.

A liquid developer includes: a carrier liquid and toner particles dispersed in the carrier liquid, including a binder resin which contains a thermoplastic resin having repeating units derived from a monomer having a styrene skeleton and repeating units derived from a monomer having an acrylic ester structure, and a thermoplastic elastomer resin that is a block copolymer, the block copolymer having a first block portion including repeating units derived from a monomer having a styrene skeleton, a second block portion including repeating units derived from an alkene having 2 to 6 carbon atoms, and a third block portion including repeating units derived from a monomer having a styrene skeleton and these block portions being bonded in this order.
摘要:
An electric motor, in which the thrust bearing action is performed by the magnetic attraction forces induced between a annular stator core with toroidal coils and magnets confronting the stator core, includes at least a cup-shaped member with a central cylindrical portion opened at the center, the cup-shaped member serving as a magnet yoke and a seat on which an element to be driven by the motor is mounted, and a cylindrical rotary sleeve press-fitted in the central cylindrical portion. This construction contributes to a reduction of the weight, size and manufacturing cost of the motor.
