Abstract
An image forming apparatus includes plural image forming devices each including an image carrier, a charger and a developing device, which in conjunction produce a corresponding toner image on the image carrier. A primary image transferring device transfers the toner images from the image carriers to an intermediate image transfer body one above the other, thereby forming a composite toner image. A secondary image transferring device transfers the composite toner image from the intermediate image transfer body to a recording medium. The primary image transferring device includes the intermediate image transfer body including at least an elastic layer, a cleaning device cleaning the intermediate image transfer body, and a coating device coating a lubricant on the intermediate image transfer body. The charger is released from the image carrier substantially at the same time as the coating device is released from the intermediate image transfer body.
