Abstract
In a medium heating device, a medium is conveyed along a conveyance path. A first contact heater contacts a back surface of the medium. A second contact heater is disposed downstream from the first contact heater in a conveyance direction of the medium and contacts the back surface of the medium. A non-contact heater faces the second contact heater across the conveyance path and heats a front surface of the medium at a position separated from the medium on the conveyance path. In an operation period in which the medium is intermittently conveyed on the conveyance path, circuitry supplies power to each of the first contact heater, the second contact heater, and the non-contact heater to generate heat, and the power supplied to the second contact heater is smaller than the power supplied to the first contact heater.
