    • An image forming apparatus includes an image forming mechanism for forming an image on a recording medium with a developer according to image data and a fixing mechanism for fixing the developer forming the image on the recording medium. The fixing mechanism includes a pressing member, a fixing member, a tension roller, and a cleaner. The fixing member and the pressing member respectively apply heat and pressure to the recording medium conveyed through a nip formed between the pressing member and the fixing member. The tension roller contacts one of the pressing member and the fixing member that contacts the developer forming the image on the recording sheet to apply tension to the one of the pressing member and the fixing member. The cleaner contacts the tension roller and removes contaminants including the developer adhered to the tension roller.
    • 图像形成装置包括用于根据图像数据用显影剂在记录介质上形成图像的图像形成机构,以及用于将形成图像的显影剂固定在记录介质上的固定机构。 固定机构包括按压部件,固定部件,张紧辊和清洁器。 固定构件和按压构件分别对通过形成在按压构件和固定构件之间的辊隙输送的记录介质施加热和压力。 张紧辊接触按压构件和与记录纸上形成图像的显影剂接触的固定构件之一,以向按压构件和定影构件中的一个施加张力。 清洁剂接触张紧辊并去除污染物,包括附着在张力辊上的显影剂。

    • A fixing device includes a rotatable fuser member, a rotatable pressure member, a heater, and a controller. The rotatable fuser member is subjected to heating. The rotatable pressure member is disposed opposite the fuser member. The pressure member presses against the fuser member to form a fixing nip therebetween, through which multiple recording media, each spaced apart from each other by an interval distance in a conveyance direction, are sequentially conveyed at a conveyance speed. The heater is disposed adjacent to the fuser member to heat the fuser member. The controller is operatively connected to the heater to control power supply to the heater through a series of on-off switching control cycles, each including an on-time during which the heater power supply is on, and an off-time during which the heater power supply is off, in synchronization with conveyance of the recording medium.
    • 定影装置包括可旋转的定影器构件,可旋转的压力构件,加热器和控制器。 可旋转的定影器构件经受加热。 可旋转的压力构件设置成与定影器构件相对。 压力构件压靠定影部件,在其间形成定影辊隙,通过该定影辊将输送方向间隔开的多个记录介质以传送速度依次传送。 加热器邻近定影器构件设置以加热定影器构件。 控制器可操作地连接到加热器,以通过一系列开 - 关切换控制循环来控制对加热器的供电,每个开关控制周期包括加热器电源打开的导通时间和加热器电源打开期间的关闭时间 与记录介质的输送同步,电源关闭。
