US 10,481,534 B2 · Image forming apparatus

Abstract

An image forming apparatus includes a fixing device configured to fix a toner to a recording medium, a cooling device disposed so as to cool the fixing device with forced air, and a rotatable guide configured to guide the recording medium towards a first location when in a first position and towards a second location when in a second position. The rotatable guide partially blocks the forced air at the first position and forms a pathway for the forced air when at the second position. A control unit rotates the guide unit to the second position if an operating mode of the fixing device is changed from a first mode having a fixing temperature set point at a first temperature to a second mode having a fixing set point temperature lower than the first temperature.

An image forming apparatus, comprising:

a fixing device configured to fix a toner to a recording medium;
a cooling device disposed so as to cool the fixing device with forced air;
a rotatable guide configured to guide the recording medium towards a first location in a first position and towards a second location when in a second position, the rotatable guide partially blocking the forced air in the first position and forming a pathway for the forced air between the cooling device and the fixing device when at the second position;
and
a control unit configured to rotate the guide unit to the second position if an operating mode of the fixing device is changed from a first mode in which the fixing unit has a set point temperature at a first temperature to a second mode in which the fixing unit has a set point temperature at a second temperature lower than the first temperature.
