摘要:
A heating fuser includes: a rotating member configured to heat a toner transferred onto a sheet; a first coil body configured to generate a first magnetic field for inducing eddy-current in a first area including the center in a rotation axis direction of the rotating member; second coil bodies configured to generate second magnetic fields for inducing eddy-current in second areas of the rotating member adjacent to the first area in the rotation axis direction; third coil bodies located to extend over the first and second coil bodies when viewed in a direction orthogonal to the rotation axis direction; and a driving circuit configured to drive the third coil bodies between a first state in which the third coil bodies generate magnetic fields for weakening the first magnetic field and a second state in which the third coil bodies generate magnetic fields for strengthening the second magnetic fields.

Disclosed is a commercially suitable method for producing a 1-substituted-5-acylimidazole compound. A 1-substituted-5-acylimidazole compound is produced with a high position selectivity by reacting an N-substituted amidine compound or a salt thereof with a ketone compound in the presence of a base.
摘要:
In an embodiment of the present invention, an electromagnetic induction coil, insulating plates, and a magnetic core are positioned by a coil holder including holder plates on which ribs are integrally formed. Consequently, the electromagnetic induction coil is regulated from sliding on the holder plates and fixed in a desired proper position regardless of flows of a mold material caused when a coil mold is injection-molded.
