摘要： An electrostatic recording method using a single surface control electrostatic recording head where the control voltage pulse is delayed for a short time after the application of the recording voltage. The delay produces a potential difference large enough to prevent a decrease in the recording density due to fluctuation of temperature and humidity.

摘要： A method of preventing the occurrence of blackened margins on a photosensitive sheet processed in an electrophotographic apparatus. The method comprises the steps of calculating a first sheet transporting length by which the photosensitive sheet is required to be transported until the forward end of an image area of the photosensitive sheet within which an image is allowed to be formed is charged with electricity and a second sheet transporting length by which the sheet is required to be further transported until the rear end of the image area is charged with electricity. A charging device is caused to turn ON when the actually transported length of the photosensitive sheet attains the calculated first sheet transporting length, and then is deactuated to turn OFF when the additionally transported length of the photosensitive sheet attains the calculated second sheet transporting length. Thus the photosensitive sheet can be charged with electricity only in its image area regardless of the overall length of the photosensitive sheet and of the position in which the photosensitive sheet is placed for exposure to the image-forming light. As a result, the margins of the photosensitive sheet, although they have not been exposed to the image-forming light or to erasing light, nevertheless attract no toner particles and so are not blackened.
