摘要： A heat-sensitive stencil sheet consisting of a porous substrate and a thermoplastic film adhered to the substrate is provided without no use of an adhesive. The porous substrate comprises a screen cloth wholly or partially consisting of conjugate fibers (a sheath-core type or a side-by-side type) one exposed component of which has an affinity with the thermoplastic resin film and having a melting point lower than that of the other component of the conjugate fiber and lower than that of the thermoplastic resin, and the screen cloth is adhered to the thermoplastic resin film through the exposed component. The heat-sensitive stencil sheet can be produced by superposing the thermoplastic resin film on the substrate and heating under pressure the superposed film and substrate at the softening point or higher of the above exposed component of the conjugate fiber and at a temperature lower than the melting point of the other component of the conjugate fiber and lower than the melting point of the thermoplastic resin.

摘要： A charging device includes a charging member to charge an image bearing member; an applying device configured to apply to the charging member a charging bias voltage comprising a DC voltage component and an AC voltage component; an AC current detector; a DC current detector; and a controller. The controller determines a saturation peak-to-peak voltage V0 at which the detected DC current saturates when a peak-to-peak voltage of the AC voltage is increased, calculates a relational expression using only a detected AC current when a peak-to- peak voltage which is not more than the saturation peak-to-peak voltage V0 is applied, and determines the peak-to-peak voltage of the AC voltage applied to the charging member in an image forming operation on the basis of the relational expression and a detected AC current when a peak-to-peak voltage higher than the saturation peak-to-peak voltage V0 is applied.

摘要： When a charging member charge a photosensitive member by being applied with a direct-current voltage, a gap between the charging member and the photosensitive member is exposed to light with a constant light amount. However, if the process speed is lowered, charging non-uniformity occurs. Therefore, when the process speed is low, the amount of light radiated to the charging gap is made higher than that when the process speed is low.
