    • A fixing apparatus includes: two rotatable members, for forming a nip, including a region where an outer diameter is increased from a longitudinal central portion toward a longitudinal end portion; a heater; and a controller for controlling a heat generation distribution of the heater. The controller is capable of controlling the heater so that the heat generation distribution of the heater is such that a heat generation amount at the longitudinal end portion is larger than that at the longitudinal central portion in a period from start of the heater until the recording material reaches the nip. A ratio of the heat generation amount at the longitudinal end portion to that at the longitudinal central portion is larger when a cumulative amount of use of the fixing apparatus is larger than a predetermined amount than when the cumulative amount of use is smaller than the predetermined amount.
    • 定影装置包括:用于形成辊隙的两个可旋转构件,包括外径从纵向中心部分朝向纵向端部部分增加的区域; 加热器 以及用于控制加热器的发热分布的控制器。 控制器能够控制加热器,使得加热器的发热分布使得在从加热器开始到记录材料的时间段期间,纵向端部处的发热量大于纵向中心部分处的发热量 到达nip 当累积使用量小于预定量时,当定影装置的累积使用量大于预定量时,纵向端部处的发热量与纵向中心部分处的发热量的比率较大 。

    • In a system having plural terminals including terminals A, B, when the terminal A is editing a data object and editing information is shared among the plural terminals, if the terminal B performs a changeover operation of displayed page, the editing operation in the terminal A is cancelled, and the editing information is deleted in the other terminals. In the terminal A, the editing information by that time is held, and when the data object is restored, the held editing information is transmitted to the other terminals. Then the initial display status is restored in the other terminals.
    • 在具有终端A,B的多个终端的系统中,当终端A正在编辑数据对象并且在多个终端之间共享编辑信息时,如果终端B执行所显示页面的切换操作,则终端A中的编辑操作 被取消,并且其他终端中的编辑信息被删除。 在终端A中,保持该时刻的编辑信息,并且当数据对象恢复时,保持的编辑信息被发送到其他终端。 然后在其他终端恢复初始显示状态。

    • The image forming apparatus, in the case where image forming is performed on a recording medium whose size covers a position of a second temperature detection element perpendicularly disposed to the recording medium conveyance direction, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a first power supply control is switched to a second power supply control. In the case where image forming is performed on a recording medium whose size does not cover a position of the second temperature detection element, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a conveyance control portion executes a control for extending the conveyance interval of the recording medium. Thus, an unduly large temperature rise in the non-sheet passing portion is prevented, and a good quality image can be provided without glossy unevenness in one sheet.
    • 在检测到的温度在执行期间检测到的温度上升到预定温度的情况下,在其尺寸覆盖垂直于记录介质输送方向的第二温度检测元件的位置的记录介质上进行图像形成的情况下, 第一电源控制,第一电源控制切换到第二电源控制。 在尺寸不覆盖第二温度检测元件的位置的记录介质上进行图像形成的情况下,当在第一电源控制执行期间检测到的温度上升到预定温度时,输送控制部分执行 用于延长记录介质的输送间隔的控制。 因此,防止非片材通过部分的过大的温度上升,并且可以在一张片材中没有光泽不均匀的情况下提供高质量的图像。
