Image forming apparatus configured to eject air toward a gap between the top end of a sheet having passed through a nip portion and the circumference of a fixing rotating member of the nip portion
摘要：
An image forming apparatus includes an air ejecting portion that ejects air toward a gap between the top end of a sheet having passed through a nip of the heating roller and a pressure roller, and the circumference of the heating roller. The air ejecting portion includes a plurality of air nozzles and a plurality of electromagnetic valves being respectively connected thereto and ejects air selectively from a plurality of air ejection positions arranged in the width direction perpendicular to the sheet conveying direction.
摘要（中）：

图像形成装置包括：空气喷射部，其朝向已经通过加热辊的辊隙的片材的顶端与加压辊之间的间隙和加热辊的周边排出空气。 空气喷射部分包括多个空气喷嘴和多个电磁阀，分别连接到其上并从与纸张传送方向垂直的宽度方向上布置的多个空气喷射位置选择性地喷出空气。
