Title:
HEATING DEVICE AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP3915305
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently heat a toner image and prevent use of a large capacity of alternating magnetic field generating source, and the generation of a leakage magnetic flux in a heating device for heating the toner image on a carrying body having a thin film-like heat generating layer by electromagnetic induction action, and providing an image forming device.
SOLUTION: An exciting coil 2 comprising a first coil 2a and a second coil 2b arranged so as to face each other on both sides of a carrying body 1 having a heat generating layer 12 on the inside is installed. The heat generating layer 12 made of a low electric-conductivity material is formed in a thin layer. The exciting coil 2 is pair coil connected by coupling magnetically adding the operations of the first coil 2a and the second coil 2b, and a power source device 3 for applying AC voltage is connected to the exciting coil 2. A magnetic flux being excited with the exciting coil 2 forms a loop passing through the heat generating layer 12, and the heat generating layer 12 is efficiently heated.
