ABSTRACT:
A method of detecting the toner density of a standard test toner image which comprises the steps of forming on the photosensitive drum a saturated test toner image from which the amount of diffused light is to be measured as a saturation level as well as the standard test toner image, and evaluating the measurement of the amount of diffused light from the standard test toner image in accordance with the measurement of the amount of diffused light from the saturated test toner image. In an image forming method or image forming apparatus which employs this toner density detecting method, the standard test toner image is formed on the photosensitive drum with a specified voltage of developing bias impressed, and an optimum developing bias voltage is calculated from the measurement of the amount of diffused light from the saturated test toner image and the measurement of the amount of diffused light from the standard test toner image. Such a process is carried out prior to an image forming operation.
