1. A conveyance device configured to convey a recording medium, the conveyance device comprising:
a heater configured to heat the recording medium, the heater having a maximum passage region corresponding to a maximum width of the recording medium;
a first temperature detector and a second temperature detector configured to detect a temperature of the heater; and
a recording medium detector configured to detect the recording medium,
wherein the first temperature detector is disposed at a position farther from a center position of a heating region of the heater than the second temperature detector in a conveyance orthogonal direction, the conveyance orthogonal direction being along a surface of the recording medium and orthogonal to a direction in which the recording medium is conveyed, the position of the first temperature detector offset from a closest edge of the maximum passage region towards the center positon of the heating region of the heater, and
wherein the recording medium detector is disposed on a side opposite to the first temperature detector with respect to the second temperature detector in the conveyance orthogonal direction.
