A conveyance device to convey a recording medium includes a heater, a first temperature detector, a second temperature detector, and a recording medium detector. The heater heats the recording medium. The first temperature detector and the second temperature detector detect a temperature of the heater. The recording medium detector detects the recording medium. 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 is along a surface of the recording medium and orthogonal to a direction in which the recording medium is conveyed. 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.
