Title:
HEATING DEVICE AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2021121873
Kind Code:
A
Abstract:
To provide a technology, in a heating device having a plurality of heat generating parts arranged side by side with an interval, that can satisfactorily perform control of the caloric value by performing appropriate temperature detection without being affected by a change in temperature due to the intervals in a direction where the plurality of heat generating parts are arranged side by side.SOLUTION: A heating device of an embodiment comprises heat generating parts and temperature sensors. The heat generating parts provided in plurality are divided into a plurality of blocks and arranged side by side on a substrate with an interval in the respective blocks. The temperature sensors have temperature detection areas in the respective blocks, are provided corresponding to the heat generating parts while avoiding the intervals, and detect the temperature of the heat generating parts with a smaller number than the number of the plurality of heat generating parts.SELECTED DRAWING: Figure 3
