    • A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. Two heating elements heat the fuser roll. One of the heating elements is configured for heating a first portion of the fuser roll while a second of the heating elements is configured for heating a second portion of the fuser roll. The second portion of the fuser roll is axially spaced from the first portion. A temperature sensing system monitors a temperature of the fuser roll in a first location and monitors a temperature of the fuser roll in a second location which is axially spaced from the first location. A control system determines an amount of power to supply to the first heating element as a function of the monitored temperatures at the first and second axially spaced locations and determines an amount of power to supply to the second heating element as a function of the monitored temperatures at the first and second axially spaced locations.
    • 定影装置包括定影辊和在其间限定辊隙的压力辊。 两个加热元件加热定影辊。 加热元件中的一个被配置用于加热定影辊的第一部分,而第二加热元件被配置用于加热定影辊的第二部分。 定影辊的第二部分与第一部分轴向间隔开。 温度感测系统在第一位置监测定影辊的温度,并且在与第一位置轴向间隔开的第二位置中监测定影辊的温度。 控制系统根据第一和第二轴向间隔位置处监测到的温度确定供应给第一加热元件的功率量,并确定供应给第二加热元件的功率的量作为监测温度的函数 在第一和第二轴向间隔的位置。
