Abstract
To ensure insulating properties between a temperature detection member and a heat conduction member.SOLUTION: A heating device comprises: a heater 23; a heat conduction member 24 that is arranged in contact with the heater 23; a holding member 25 that has, on a first surface, a holding part that holds the heater 23 and the heat conduction member 24; and a temperature detection member 27B that is arranged closer to the center in a short direction Y that is a direction orthogonal to a longitudinal direction X of the heat conduction member 24 than both ends Z1 and Z2 in the short direction Y, along a surface of the heat conduction member 24 in contact with the heater 23. The heat conduction member 24 has locking parts 24d1 and 24d2 that can be locked to a second surface on the opposite side of the first surface of the holding member 25. The locking parts 24d1 and 24d2 are provided separate from the temperature detection member 27B at both ends Z1 and Z2 in the short direction Y of the heat conduction member 24.SELECTED DRAWING: Figure 7
