    摘要: An image forming apparatus includes a heater, a first temperature sensor, a second temperature sensor, and processing circuitry. The heater is configured to heat a medium on which an image is formed. The first temperature sensor is configured to measure a temperature of the heater. The second temperature sensor is configured to measure a temperature of a region heated by the heater. The processing circuitry is configured to control the temperature of the heater. The processing circuitry is configured to control the heater based on a comparison between a measured temperature of the first temperature sensor and a first threshold value, and a comparison between a measured temperature of the second temperature sensor and a second threshold value.

    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: A liquid discharge apparatus includes a conveyor to repeat conveyance of a recording medium by a predetermined distance and stop of conveyance of the recording medium; a liquid discharge head to discharge a liquid onto the recording medium; an irradiation device disposed downstream from the liquid discharge head in a direction of conveyance of the recording medium, to irradiate, with an electromagnetic wave, the recording medium onto which the liquid has been discharged by the liquid discharge head; and circuitry configured to control the irradiation device to irradiate the recording medium. The circuitry is configured to set a first irradiation amount during the stop of conveyance to a larger value than a value of a second irradiation amount during the conveyance of the recording medium.
