    • A fixing device for fixing on a recording material a toner image formed on the recording material includes a flexible sleeve including a resinous base layer, a parting layer and an adhesive layer for bonding the base layer and the parting layer; a heater contacted to an inner surface of the sleeve; a pressing member for forming a nip, in which the recording material on which the toner image has been formed is nipped and conveyed, between itself and the sleeve to which the heater is contacted; a voltage applying member for applying a voltage, of a polarity identical to a polarity of toner; and a grounding member, contactable to the recording material in a nipped state in the nip, for grounding the recording material. In a thickness direction of the layers, an electric resistance of the adhesive layer is larger than that of the parting layer and the electric resistance of the parting layer is larger than that of the base layer. The voltage applying member applies the voltage to the sleeve in contact with the base layer.
    • 用于固定在记录材料上的调色剂图像形成在记录材料上的调色剂图像包括具有树脂基层,分型层和用于粘接基层和分型层的粘合层的柔性套筒; 与套筒的内表面接触的加热器; 用于形成辊隙的按压构件,其中已经形成有调色剂图像的记录材料在其与加热器接触的套筒之间被夹持和传送; 用于施加极性与调色剂的极性相同的电压的施加电压部件; 以及接地构件,其能够在夹持部中以夹持状态与记录材料接触,用于使记录材料接地。 在层的厚度方向上,粘合剂层的电阻大于分离层的电阻,分离层的电阻大于基底层的电阻。 电压施加部件将电压施加到与基底层接触的套筒。
