Patent ID: 8755706

Claim:
An image forming apparatus configured to form an image on a recording material, the image forming apparatus comprising: an image forming device configured to form a toner image on the recording material; a fixing device configured to fix the toner image onto the recording material by heating the recording material bearing the toner image at a nip portion while conveying the recording material; a first cooling fan configured to supply air to a first area which is situated at an end potion of the fixing device in a direction orthogonal to a recoding material conveyance direction; a second cooling fan configured to supply air to a second area which is situated at an end portion of the fixing device on the side opposite to the first area; a first temperature detector for detecting a temperature of the first area; a second temperature detector for detecting a temperature of the second area; and a control unit configured to start to operate the first cooling fan based on a detected temperature obtained by the first temperature detector and the second cooling fan based on a detected temperature obtained by the second temperature detector, wherein, when the recording material is displaced toward the first area and a positional displacement amount of a recording material with respect to a conveyance reference for the recording material is a predetermined amount or larger, the control unit sets a temperature for starting to drive the second cooling fan to be lower than a temperature that is set when the positional displacement amount is less than the predetermined amount.
