摘要： The image forming apparatus calculates a surface voltage of an image bearing member based on a first charge start voltage, which is obtained when a first voltage application section applies a first DC voltage to a charge section, and a second charge start voltage, which is obtained when a second voltage application section applies a second DC voltage to the charge section. This allows a high-quality image to be formed irrespective of a change in circumstance or drum layer thickness.
摘要翻译：图像形成装置基于当第一电压施加部分向充电部施加第一DC电压时获得的第一充电开始电压和获得的第二充电开始电压来计算图像承载部件的表面电压当第二电压施加部分向充电部施加第二DC电压时。这允许形成高质量的图像，而不管环境或鼓层厚度的变化。

摘要： The high-voltage output apparatus includes a voltage application part that applies a DC voltage to the charge member; a current detection part that detects a value of a current flowing in the image bearing member when the DC voltage is applied to the charge member; and a control part that calculates a plurality of discharge start voltages for the image bearing member, based on a plurality of current values detected by the current detection part as a result of the voltage application part applying a plurality of different DC voltages to the charge member, and controls the DC voltage applied to the charge member, using the plurality of calculated discharge start voltages. Consequently, a high-quality image can be formed by maintaining a potential on a photosensitive drum to be constant irrespective of the states of the circumstances and/or the drum layer thickness.
摘要翻译：高电压输出装置包括向充电部件施加直流电压的电压施加部; 电流检测部，其在对所述充电部件施加所述直流电压时，检测在所述图像承载部件中流动的电流的值; 以及控制部，其基于由所述电流检测部检测出的多个电流值，对作为所述图像承载部件的多个放电开始电压进行计算，所述多个电流值作为施加电压的结果，所述电压施加部向所述充电部件施加多个不同的直流电压并且使用多个计算出的放电起始电压来控制施加到充电部件的直流电压。因此，通过将感光鼓上的电位保持恒定，可以形成高质量的图像，而与环境状态和/或鼓层厚度无关。

摘要： Sheets fed out from a sheet feeding portion, which is brought into pressure contact with the sheets by the upward movement of a sheet stacking portion to feed out the sheets, are separated and conveyed one by one while being upwardly curved. During the sheet feeding operation, the sheet stacking portion is sequentially moved up, and when the sheet feeding operation is completed, the sheet stacking portion is moved down. Further, a remaining amount indicating member moved with the upward movement of the sheet stacking portion to indicate the remaining amount of sheets is held at a position before the sheet stacking portion is moved down, by a holding mechanism, when the sheet feeding operation is completed and the sheet stacking portion is moved down.
