摘要：In an image forming apparatus of the present invention, the voltage of achargeable layer (2b) of an image carrier (2) at the portion to be in contact with writingelectrodes (3b) is adjusted by a surface potential adjusting member (8) which is disposed
to be in contact with the chargeable layer (2b) between the writing electrodes (3b) and atransfer roller (6a). That is, even if the reverse charge injection occurs because thetransfer voltage is applied to the transfer roller (6a) and the transfer roller (6a) is incontact with the chargeable layer (2b) of the image carrier (2) at an interval between aprinted paper (5) and the next paper (5), the potential of the chargeable layer (2b) at theportion to be in contact with the writing electrodes (3b) is adjusted not to exceed thewithstand voltage of IC drivers (7) of the writing electrodes (3b) by the surface potentialadjusting member (8). Therefore, this prevents the writing head (3) from being broken,prevents the production of ghost image, and further inhibits voltage drop due todischarge between the image carrier and the writing electrodes during the process ofwriting a latent image, thereby preventing the electrostatic latent image from being indisorder.
