Abstract

An image forming apparatus is provided with an image bearing member for bearing a toner image while rotating, a developing device including a developing roller for supplying toner to a surface of theimage bearing member and a pair of gap rollers held in contact with opposite end portions of the image bearing member to define a specified gap between the developing roller and the surface of the image bearing member, and a lubricant applicator for applying a lubricant to parts of the opposite end portions of the image bearing member where the gap rollers are in contact.

Description

technical field [0001] The present invention relates to an image forming apparatus having an image carrier on which a toner image is formed on the surface, and an image forming unit used in the image forming apparatus. Background technique [0002] An electrostatic latent image is formed on the peripheral surface of a photosensitive drum (image carrier) by reading an original image, or based on image information transmitted from an external computer, etc., and toner is supplied to the electrostatic latent image from a developing device, in which An image forming apparatus having a structure in which a toner image is formed on a peripheral surface and the toner image is transferred onto paper is known. [0003] In such an image forming apparatus, due to the residual toner remaining on the peripheral surface of the photosensitive drum after the transfer process on the paper, or the application of a high voltage before forming an electrostatic latent image attached to the perip...
