    • 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.
    • 本发明的目的在于改进图像形成方法,其中离子电流以图像形式被调制,基于此,在记录片材,绝缘鼓和其它记录介质上形成二次静电潜像,并且, 从而形成静电潜像。 更详细地说,形成这种二次静电潜像的这种片材和滚筒的整个区域预先均匀地充电到期望的电位,从而在显影时发生起雾现象,并且形成的图像发生变化 可以防止由于离子电流调制元件的劣化导致的离子电流的调制量的变化。 可以通过例如改变施加到设置在电晕放电器中的栅格的电压来进行在其上形成其上所需的任意电位的二次静电潜像的部件的设定。
