摘要： 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.

摘要： A heating device includes a pre-heater configured to pre-heat a medium, onto which a liquid is discharged from a liquid discharger, at a first position upstream of the liquid discharger in a conveyance direction of the medium, a print-heater configured to heat the medium at a second position opposite the liquid discharger, a post-heater configured to post-heat the medium at a third position downstream of the second position in the conveyance direction, and circuitry configured to control a temperature of each of the pre-heater, the print-heater, and the post-heater. The pre-heater includes a first pre-heater and a second pre-heater disposed closer to the print-heater than the first pre-heater, and the circuitry controls a temperature of the second pre-heater to be between a temperature of the first pre-heater and the temperature of the print-heater.

摘要： An inkjet image forming apparatus is provided. The inkjet image forming apparatus includes a recording unit, a selection heater, a heater, and a processor. The recording unit forms an ink image on a recording medium being conveyed. The selection heater is disposed downstream from the recording unit relative to a direction of conveyance of the recording medium, and selectively heats the ink image formed on the recording medium. The heater is disposed downstream from the selection heater relative to the direction of conveyance of the recording medium, and heats the recording medium on which the ink image has been selectively heated. The processor controls the recording unit, the selection heater, and the heater, and sets an output of the selection heater in view of an occurrence of cockling on the recording medium.
