Patent ID: 7106985

Claim:
An image forming system comprising: a manuscript image reading device to scan a manuscript and obtain shade information on the manuscript; an exposure/development device to record a charged latent image in a photosensitive body based on the shade information obtained by said manuscript image reading device, to apply toners to the photosensitive body to transfer the toners to a recording medium; a fixing device to fix the toners transferred to the recording medium by thermal pressing; said fixing device having; a rotational heating member; a pressing roller for pressing from a bottom of the rotational heating member; and a non-contact temperature detector that is provided above a horizontal surface passing a rotation axis of the rotational heating member and detects a temperature of said rotational heating member; and a fan to direct heat convection generated by said rotational heating member to directions other than the direction of said non-contact temperature detector, wherein heating of the rotational heating member is controlled by a value detected by said non-contact temperature detector, and wherein said fan is disposed in a position symmetrical with the non-contact temperature detector, with the heating roller as a center, and the fan exhausts air flow outwardly.
