摘要： An image forming apparatus includes a process cartridge that includes an image bearer including a rotary shaft and rotates about the rotary shaft; a charger to charge a surface of the image bearer; and a developing device to develop an electrostatic latent image formed on the image bearer into a visible toner image. The charger includes a charging roller that rotates about a shaft together with the image bearer during image formation and electrically charges a surface of the image bearer. A surface linear speed of the charging roller is made slower than a surface linear speed of the image bearer. The image forming apparatus includes a charging roller controller that switches the rotational speed of the charging roller to a first rotational speed slower than the linear speed of the image bearer and a second rotational speed identical to the linear speed of the image bearer.

摘要： A lubricant supplying device includes a lubricant supplier contacting an image bearer, a solid lubricant contacting the roller, a detector detecting a lubricant amount, and a controller controlling a supplying of the roller based on a detector detection. The detector outputs to the controller a first signal of a near-end state when the amount reaches a first amount, a second signal of an end state when the amount reaches a second amount smaller than the first amount, and a third signal of an absolute end state when the amount reaches a third amount smaller than the second amount. The controller temporarily stops the supplying when the second signal is output, cancels a roller temporary stopped state even when lubricant replacement is not completed after this state, stops the supplying when the third signal is output, and maintains a roller stopped state until the replacement is completed after this state.
