发明名称 Image forming apparatus with reduced charge leakage
摘要 An image forming apparatus includes an image carrier whose surface is moved in a specific direction, a charging device to charge the image carrier, an exposure device to form an electrostatic latent image by exposing a surface of the charged image carrier, a developing device to supply a developer to the image carrier on which the electrostatic latent image is formed, a transfer device to transfer a developer image formed on the surface of the image carrier onto an image forming medium, and a dielectric member that extends from the charging device to the vicinity of the image carrier and is disposed between the charging device and the image carrier surface part exposed by the exposure device, in which the charging device, the exposure device, the developing device and the transfer device are sequentially arranged around the image carrier along the movement direction of the surface of the image carrier.

主权项 1. An image forming apparatus comprising: an image carrier whose surface is moved in a specific direction; a charging device to charge the image carrier; an exposure device to form an electrostatic latent image by exposing a surface of the charged image carrier in accordance with an image signal; a developing device to supply a developer to the surface of the image carrier on which the electrostatic latent image is formed; a transfer device to transfer a developer image formed on the surface of the image carrier onto an image forming medium; and a dielectric member having a dielectric constant of 5 or less and having an end that extends towards the image carrier with a gap of predetermined distance between the surface of the image carrier and the end, configured to be disposed between the charging device and the image carrier surface part exposed by the exposure device.
