Abstract
According to an embodiment, a fixing device includes a cylindrical body that rotates about an axial direction and a heater that heats the cylindrical body. The heater includes a substrate with a length direction matching the axial direction. The substrate has a first portion with a width in a width direction that is greater than a width of a second portion in the width direction. A first heating element is on a central portion of the substrate overlapping with the second portion. A first temperature sensing element is at a position along the axial direction that does not overlap with the second portion.
