FIELD

Embodiments described herein relate generally to an image forming apparatus and a control method.

BACKGROUND

There is an image forming apparatus that includes an on-demand fixing device capable of reducing power consumption used in fixing images to a sheet. At the ends of the fixing device in the main scanning direction, there may be regions through which sheets pass only in some cases, and therefore temperature in these regions may easily increase.

When such temperature increases occur, printing speed or the like may have to be reduced to permit the temperature to decrease. As a result, the performance of the image forming apparatus may deteriorate. If a fan must be provided in the imaging apparatus so that the temperature in these regions of the fixing device does not unwantedly increase, then cost of the image forming apparatus may have to increase.
