    摘要： A fixing device includes a fixing rotator and an opposed rotator pressed against the fixing rotator to form a fixing nip therebetween. A primary heater is disposed opposite the fixing rotator in a circumferential span of the fixing rotator other than the fixing nip in a circumferential direction of the fixing rotator to heat the fixing rotator. A heat shield is interposed between the primary heater and the fixing rotator and disposed outboard from at least a decreased size recording medium conveyance span of the fixing rotator spanning in an axial direction of the fixing rotator where a recording medium having a decreased size in the axial direction of the fixing rotator is conveyed. The heat shield shields the fixing rotator from the primary heater. A secondary heater is mounted on the heat shield to heat the fixing rotator.

    摘要： A fixing device includes a primary heater disposed opposite a fixing rotator to heat a circumferential span of the fixing rotator other than a fixing nip formed between the fixing rotator and a pressure rotator and a secondary heater disposed outboard from the primary heater in an axial direction of the fixing rotator to heat the fixing rotator at the fixing nip. The primary heater and the secondary heater heat a bi-heating span of the fixing rotator in the axial direction thereof. The secondary heater heats a mono-heating span of the fixing rotator in the axial direction thereof and generates a decreased amount of heat to be conducted to the bi-heating span of the fixing rotator. The decreased amount of heat is smaller than an increased amount of heat to be conducted to the mono-heating span of the fixing rotator that is heated by the secondary heater only.

    摘要翻译： 定影装置包括与固定旋转体相对设置的主加热器，用于加热固定旋转器的周向跨度，而不是在固定旋转体和压力旋转体之间形成的定影辊隙和从主加热器的外侧沿轴向方向设置的二次加热器 固定旋转器用于在定影辊隙处加热定影旋转器。 主加热器和二次加热器沿固定转子的轴向加热固定转子的双加热跨度。 二次加热器沿固定旋转器的轴向加热固定旋转器的单加热跨度，并且产生传导到定影旋转器的双加热跨度的减少的热量。 减少的热量小于仅由二次加热器加热的定影转子的单加热跨度的加热量。
