摘要： An image forming apparatus includes a plurality of heaters, a plurality of temperature sensors, an object sensor, and control circuitry. The temperature sensors are formed at positions corresponding to the heaters. The object sensor is configured to detect an overlap region of a medium and the heaters. The control circuitry is configured to correct temperature information acquired by the temperature sensors, according to the overlap region detected by the object sensor and the positions of the temperature sensors, and control the heaters based on the corrected temperature information.

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.
