Title:
IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP3206171
Kind Code:
B2
Abstract:
PURPOSE: To assure dealing with thicknesses and material quality of photosensitive materials, an improvement in fixing performance by smooth transportation and good image quality of full-color copies and both-side copies.
CONSTITUTION: The transporting speed of a belt 3 and the rotating speed of a fixing device are set at standard speeds (high speeds) to eliminate a bite detect before the specific recording material thick paper and paper for OHP, etc.) is bitten into the inlet of a nip part 40. The transporting speed during the recording material 16 is transported in the nip part 40 of the fixing device is set at a low speed together with both of the transporting speed of the belt 3 and the rotating speed of the fixing device to improve fixability. Further, a blade 58 is brought into contact with the surface of a press roll 54 to decrease the atm. of a release agent 65 absorbed on the roll surface nearly to zero, by which the service life of the roll is prolonged without decreasing the amt. of the release agent applied on the recording material 16 and the amt. of the release agent is held within the amt. to assure good penetratability. Good images are thus obtd. Further, the pressurization between the fixing roll 52 and the press roll 54 is released and a peeling member 18 is brought into contact with the surface of the roll 54 in the event of generation of a jam. The jammed paper is then guided with the peeling member 18 and is moved in a discharge direction.
