Abstract
An image forming apparatus including a sheet storage portion in which a plurality of sheets is stored; a heater which heats air; a fan which sprays air on the sheet stored in the sheet storage portion; and a controller which controls the heat of the heater and controls the drive of the fan, in which the controller controls the heat of the heater at a first temperature before a drive time of the fan reaches a threshold value set in advance, the drive time being in which the fan sprays air heated by the heater on the sheet, and when the drive time of the fan reaches or exceeds the threshold value set in advance, controls the heat of the heater at a second temperature lower than the first temperature.
Claims6
An image forming apparatus comprising:
- a sheet storage portion in which a plurality of sheets is stored;
- a heater which heats air;
- a fan which sprays air on the sheet stored in the sheet storage portion;
- and
- a controller which controls the heat of the heater and controls the drive of the fan,
- wherein in a case that a length of the sheet in a conveying direction of the sheet exceeds a predetermined length, the controller controls the heat of the heater at a first temperature before a drive time of the fan reaches a threshold value set in advance, the drive time being in which the fan sprays air heated by the heater on the sheet, and when the drive time of the fan reaches or exceeds the threshold value set in advance, controls the heat of the heater at a second temperature lower than the first temperature, and
- wherein in a case that the length of the sheet in the conveying direction of the sheet is equal to or less than the predetermined length, the controller controls the heat of the heater at the first temperature and the sheet is blown by the fan with heated air.
