Claims

[Claims for Utility Model Registration] (1) An endless conveyor belt is wound around at least two belt support rollers, one of which has a crown shape, and the conveyor roller is brought into pressure contact with the conveyor belt. While constituting the fixing device,
A roller-type sheet conveyance means whose sheet conveyance speed is set to be slightly higher than the sheet conveyance speed by the conveyor belt is disposed immediately downstream of the belt-type fixing device and near the center in the width direction of the conveyor belt. A sheet fixing/conveying device in an image forming apparatus, characterized in that: (2) On both sides of the sheet conveying means, second roller-type sheet conveyors whose sheet conveying speed is slightly lower than the sheet conveying speed by the sheet conveying means and slightly higher than the sheet conveying speed by the conveying belt. A sheet fixing/conveying device in an image forming apparatus according to claim (1), further comprising means.
