定影装置以及图像形成装置
摘要：
本发明涉及定影装置以及图像形成装置。设有金属部件(22)，其固定设置为在除夹持部的位置与定影带(21)的内周面对向，加热定影带(21)，且通过固定设置在其内周面侧的加热机构被加热。加热机构包括加热金属部件(22)的宽度方向中央部的第一加热器(25A)，以及加热金属部件(22)的宽度方向两端部的第二加热器(25B)。该第一加热器(25A)和第二加热器(25B)沿着金属部件(22)内周面并列设置，与该内周面对向。提供即使加热时间或首张打印时间短、装置高速化场合，也不产生定影不良等、定影带的非通纸区域难以发生过度升温的定影装置以及图像形成装置。
摘要（英）：

The present invention relates to a fixing device and an image forming apparatus. The fixing device is provided with a metal component (22) which is fixedly equipped at a position except for a fixing part and is opposite from an inner circumferential surface of a fixing strip (21). The fixing belt (21) is heated through a heating mechanism that is fixedly equipped at the inner circumferential surface side. The heating mechanism comprises the following components: a first heater (25A) which heats a central part in the width direction of a metal component (22), and a second heater (25B) which heats two ends in the width direction of the metal component (22). The first heater (25A) and the second heater (25B) are arranged side by side along the inner circumferential surface of the metal component (22) and are opposite with the inner circumferential surface. The fixing device which does not generate inferior fixing or excessive temperature increase of a paper non-passing area of the fixing belt at the state with short heating time or short first printing time and high speed of the device, and an image forming apparatus are provided.
