    • The deterioration of an error characteristic obtained at a point where a transfer method is changed is suppressed. A first adder calculates a SM value obtained when the state 00 is changed to the state 00, and outputs it to a comparator. A second adder calculates a SM value obtained when the state 01 is changed to the state 00, and outputs it to the comparator. The comparator compares the SM values, selects a path having the larger likelihood, and outputs to a register having a set and a reset. An ACS controller detects a condition in which the state transition of fixed information TAB1 is uniquely determined, and outputs a reset signal to the register having a set and a reset, which stores the SM value of that state, to set the value of the register to zero. The ACS controller 85 also outputs set signals to registers having sets and resets, which store the SM values of the states other than the state 00 of the fixed information TAB1, to set them to the maximum value.
    • 在转印方法改变的点处获得的误差特性的劣化被抑制。 第一加法器计算当状态00改变为状态00时获得的SM值,并将其输出到比较器。 第二加法器计算当状态01改变为状态00时获得的SM值,并将其输出到比较器。 比较器比较SM值,选择具有较大似然度的路径,并输出到具有置位和复位的寄存器。 ACS控制器检测固定信息TAB1的状态转移被唯一地确定的状态,并且向具有存储该状态的SM值的集合和复位的寄存器输出复位信号,以设置寄存器的值 到零。 ACS控制器85还将设置信号输出到具有集合和复位的寄存器,该寄存器存储除固定信息TAB1的状态00之外的状态的SM值,以将它们设置为最大值。

    • A fixing device includes a pressurization member connected to a pressing rotary body to press the pressing rotary body against a fixing rotary body; a depressurization assembly interposed between the pressing rotary body and the pressurization member and movable between a reduced pressure position where the depressurization assembly causes the pressurization member to press the pressing rotary body against the fixing rotary body with reduced pressure therebetween and an enhanced pressure position where the depressurization assembly is free from pressure from the pressurization member to cause the pressurization member to press the pressing rotary body against the fixing rotary body with enhanced pressure therebetween; a positioner separatably contacting the depressurization assembly to immovably halt the depressurization assembly at the enhanced pressure position; and a position detector separatably contacting the depressurization assembly to detect the position of the depressurization assembly.
    • 定影装置包括加压构件,其连接到按压旋转体以将按压旋转体按压在定影旋转体上; 减压组件,其插入在所述按压旋转体和所述加压构件之间,并且可在所述减压组件使所述加压构件在减压部件之间以减压的方式将所述按压旋转体按压在所述定影旋转体上的减压位置和压力​​位置之间移动, 减压组件没有来自加压构件的压力,从而使加压构件在压力旋转体之间以较高的压力将压力旋转体压靠固定旋转体; 定位器可分离地接触减压组件,以在增压压力位置不可动地停止减压组件; 以及位置检测器,其与所述减压组件分离地接触以检测所述减压组件的位置。
