摘要： An image forming apparatus includes: a photoconductor; a charger configured to charge the photoconductor, the charger including a discharge wire and a grid; a voltage applying circuit configured to generate charge voltage and apply the charge voltage to the discharge wire of the charger; a grid-current detector configured to detect a grid current passing through the grid; a controller configured to control the voltage applying circuit on the basis of a detection value detected by the grid-current detector so that the grid current is constant; an abnormal-discharge detector configured to detect an abnormal discharge occurring in the charger; and a suppression resistor configured to suppress abnormal discharge energy. The suppression resistor includes a first terminal and a second terminal. The first terminal is connected to the grid. The second terminal is connected to at least one of the grid-current detector and the abnormal-discharge detector.

摘要： Each parameter is provided with increase/decrease switches and a slider. In a case where a user desires seamless rough control of the value of a target parameter, the user is to use the slider. In a case where the user desires easy control of the value of the parameter with the smallest unit of the resolution, the user is to use the increase/decrease switches. Since the slider specifies a parameter value in accordance with the position of the manipulated slider, the range within which the parameter value can change is determined on the basis of the current parameter value and the maximum value and the minimum value of the parameter. Because the increase/decrease switch increases/decreases a parameter value by “1” at each manipulation, the range within which the parameter value can change by a single manipulation of the increase/decrease switch is “±1”.
