Abstract
An image forming apparatus includes an image carrier, a charging device to charge a surface of the image carrier, disposed across a predetermined gap from the image carrier, a latent image forming device, a developing device to develop a latent image formed on the image carrier into a toner image, a transfer unit to transfer the toner image from the image carrier onto a recording medium, a cleaning member to clean the image carrier after the toner image is transferred therefrom, a lubricant application member to lubricate the image carrier, a polarity adjustor to adjust polarities of the toner and lubricant adhering to the image carrier to be identical to a polarity of a charging bias. The polarity adjustor is disposed facing the image carrier, upstream from the charging device and downstream from the transfer unit in a direction in which the image carrier rotates.
