摘要： A heating device includes a heater to heat an object to be heated, a temperature detector to detect a surface temperature of the heater, a power calculator to calculate a power consumption of the heater, an abnormality detector to detect an abnormality of the temperature detector, and circuitry to cause the heater to increase the surface temperature of the heater from a first temperature to a second temperature higher than the first temperature; cause the power calculator to calculate the power consumption of the heater increased to the second temperature; cause the abnormality detector to compare the power consumption calculated by the power calculator and a predetermined threshold value; and cause the abnormality detector to determine that the temperature detector is abnormal when the power consumption calculated by the power calculator is equal to or larger than the predetermined threshold value.

摘要： A drying device includes a contact heater unit to contact and heat a medium. The contact heater unit includes a plurality of heating members each having a curved contact face to contact the medium among plural heating members of the plurality of heating members to contact a first surface of the medium opposite a second surface of the medium on which liquid is applied. The plurality of heating members includes a first heating member and a plurality of second heating members. The first heating member has a maximum contact distance to contact the medium. The plurality of second heating members is disposed upstream from the first heating member in a direction of conveyance of the medium. Two heating members of the plurality of second heating members immediately upstream from the first heating member in the direction of conveyance of the medium contact the first surface of the medium.
