Abstract
A fixing device includes a fixing unit having heat sources each extending in a longitudinal direction thereinside, and sensors that measure a surface temperature of the fixing unit. The heat sources are provided at different positions in a projection diagram of the fixing device seen in a rotational-axis direction of the fixing unit. A first measurement position for a first sensor is different in the peripheral direction from a second measurement position for a second sensor. A sum of a first distance between the first measurement position and a first heat source nearest to the first measurement position and a second distance between the second measurement position and a second heat source nearest to the second measurement position is smaller than a sum of the first and second distances in a case where the second measurement position coincides with the first measurement position in the peripheral direction.
