AI Technical Summary

Technical Problem

In existing technologies, the sheet material is prone to wrinkles when passing through the fixing device, which affects the quality of image formation.

Method used

The heating device employs a design where the two ends of the pressure roller protrude radially by a first amount compared to the central portion, and the central portion of the retainer protrudes axially by a second amount greater than the first amount compared to the two ends, forming a clamping portion to clamp and transport the sheet material, thereby suppressing the formation of wrinkles.

Benefits of technology

It effectively suppressed sheet wrinkles, improved the quality and uniformity of image formation, and ensured fixing performance.

Abstract

提供一种加热装置以及图像处理装置,能够抑制片材的褶皱。实施方式的加热装置具有筒状的带、加热器、加压辊和保持件。加热器配置在带的内侧,并以带的轴向作为长度方向。加压辊能够在加热器的相反侧与带抵接而形成夹持部。加压辊进行旋转而能够输送夹在夹持部的片材。加压辊的长度方向的两端部与中央部相比向径向突出第一突出量。在保持件中,配置有加热器的第一方向的第一面为平面。在保持件中,与第一方向相反的第二方向的第二面中的长度方向的中央部与两端部相比向第二方向突出第二突出量。第二突出量大于第一突出量。
