    • A fixing device configured to thermally fix a developing agent image to a recording sheet includes a fixing belt having a tubular shape defining an inner space, a heat generating member, a nip member, and a stay which are disposed in the inner space of the fixing belt, and a rotating member disposed outside the inner space of the fixing belt. The fixing belt is nipped between the nip plate and the rotating member. The stay comprises a first receiving portion and a second receiving portion which are positioned upstream and downstream of the heat generating member, respectively, in a conveying direction of the recording sheet and are configured to receive a force exerted from the rotating member to the nip member. The heat insulator is disposed between the nip member and one of the first receiving portion and the second receiving portion of the stay.
    • 构造成将显影剂图像热固定到记录片材的定影装置包括具有限定内部空间的管状形状的定影带,发热元件,夹持部件和支架,所述定影带设置在固定件的内部空间中 带,以及设置在定影带的内部空间外侧的旋转构件。 定影带夹在夹板和转动件之间。 支架包括分别位于记录纸的输送方向上位于发热元件的上游和下游的第一接收部分和第二接收部分,并且被构造成接收从旋转部件施加到压印部件的力 。 隔热件设置在夹持构件与支架的第一容纳部分和第二容纳部分之一之间。

    • A developer supply device is provided, which includes a transfer board including an activating section and an always-transferring section. The activating section is disposed in a position close to a developer holding member and lower than a position where development agent is transferred onto the developer holding member. The activating section is supplied with an activating voltage for making the development agent leave a developer transfer path and drop into the developer storage section during an activating process performed at an initial stage of a developer transferring operation while supplied with the transfer bias voltage after the activating process. The always-transferring section is disposed across a position facing the developer storage section to a position lower than and adjacent to the activating section, and always supplied with a transfer bias voltage during the developer transferring operation.
    • 提供一种显影剂供应装置,其包括转印板,该转印板包括激活部分和总是转印部分。 激活部分设置在接近显影剂保持部件的位置,并且低于显影剂被转印到显影剂保持部件上的位置。 激活部分被提供有用于使显影剂离开显影剂转移路径的激活电压,并且在显影剂转印操作的初始阶段执行的激活过程中并且在激活之后被提供转印偏压时被投入到显影剂存储部分 处理。 始终传送部分跨越面向显影剂存储部分的位置设置到低于并与激活部分相邻的位置,并且在显影剂传送操作期间始终被提供转印偏压。
