摘要： The present invention aims at improvement in the image forming method, wherein ion current is modulated in an image form, on the basis of which a secondary electrostatic latent image is formed on a recording sheet, an insulated drum, and other recording media, and the thus formed electrostatic latent image is developed. In more detail, the entire region of such sheet and drum where such secondary electrostatic latent image is formed is uniformly charged beforehand to a desired potential, whereby the fogging phenomenon to occur at the time of development, and changes in the formed image which take place due to variations in the modulating quantity of the ion current on account of deterioration in an ion current modulating element can be prevented. Setting of the member to form thereon such secondary electrostatic latent image at a desired arbitrary potential can be done by, for example, varying the voltage to be applied to a grid provided in a corona discharger.
