Abstract
An image formation apparatus includes: a transferrer that forms a toner image on an image formation surface of paper; a fixer that fixes the toner image on the paper; a paper conveyor that conveys the paper between an upstream side of the transferrer and a downstream side of the fixer in a paper conveyance direction; and a paper pre-heater that heats, on the upstream side of the transferrer in the paper conveyance direction, the image formation surface of the paper.
Claims16
An image formation apparatus comprising:
- a transferrer that forms a toner image on an image formation surface of paper;
- a fixer that fixes the toner image on the paper;
- a paper conveyor that conveys the paper between an upstream side of the transferrer and a downstream side of the fixer in a paper conveyance direction;
- a paper pre-heater that heats, on the upstream side of the transferrer in the paper conveyance direction, the image formation surface of the paper;
- a temperature sensor configured to detect a fixing temperature of the fixer;
- and
- a controller configured to:
- turns on the paper pre-heater when the fixing temperature of the fixer detected by the temperature sensor is equal to or lower than a first predetermined temperature;
- and
- turns off the paper pre-heater when a paper temperature of the image formation surface of the paper at an inlet of the fixer is equal to or higher than a second predetermined temperature.
