    • Within a fixing roller (231) are disposed a main heater lamp (234a) for heating a central portion of the fixing roller and a sub-heater lamp (235a) for heating opposite end portions of the fixing roller. MRnh, SRnh and ΣRnh satisfy the formula (1) or (2): ΣRnh≧30.5·Ln(Ht)+382  formula (1) MRnh≦−21.9·Ln(Ht)−198  formula (2), where MRnh is a mean value of heat distribution in a no-heat generating section of the main heater lamp; SRnh is a mean value of heat distribution in the a no-heat generating section of the sub-heater lamp; ΣRnh is the sum total of these mean values; and Ht=vp/(Mh·λ) where vp is a fixing speed (m/s), Mh a heat capacity per unit length of the heating member (J/(° C.·m)) and λ a heat conductivity of a material forming the heating member (W/(m·° C.)).
    • 在定影辊(231)内设置有用于加热定影辊的中心部分的主加热灯(234a)和用于加热定影辊相对端部的副加热灯(235a)。 MRnh,SRnh和SigmaRnh满足公式(1)或(2):<?in-line-formula description =“In-line Formulas”end =“lead”?> SigmaRnh> = 30.5.Ln(Ht)+382 formula (1)<?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?> MRnh <= -21.9.Ln(Ht)-198式(2),<?in-line-formula description =“In-line Formulas”end =“tail”?>其中MRnh是无热分布的平均值 主加热灯的发电部分; SRnh是副加热灯的无热生成部的热分布的平均值; SigmaRnh是这些平均值的总和; 和Ht = vp /(Mh.lambda)其中vp是定影速度(m / s),Mh是加热构件的每单位长度的热容(J /(℃))和λ的热导率 形成加热构件的材料(W /(m℃))。

    • Structure is provided to efficiently discharge sheets outputted from an image forming apparatus to a plurality of bins. In a copier, for an original supplied from a document feeder, an image forming apparatus forms an image on a sheet supplied from a sheet feeder, and the sheet is discharged through a sheet discharging port. A sheet outputting apparatus receives discharged sheets through a sheet receiving port. In accordance with information of a job relating to the sheets copied supplied through an operation panel, a control unit causes the sheets to be distributed to be discharged to a plurality of bins. The number of acceptable sheets to each bin is detected by a detecting device. A control unit controls discharge of sheets to that the number of bins is a minimum, so that discharge to bins is easily conducted in a subsequent copying job.
    • 提供结构以有效地将从图像形成装置输出的纸张排出到多个箱。 在复印机中,对于从送纸器提供的原稿,图像形成设备在从供纸器供应的片材上形成图像,并且片材通过片材排出口排出。 纸张输出装置通过纸张接收端口接收排出的纸张。 根据与通过操作面板提供的复印件相关的作业的信息,控制单元使得纸张被分配以排出到多个箱。 通过检测装置检测每个箱的可接受片材的数量。 控制单元控制纸张的排出量使得箱的数量最小,使得在随后的复印作业中容易进行到箱的排出。
