| Summary: | An image forming method includes detecting a toner degradation state by detecting an image density on an electrostatic latent image carrier with high sensitivity and low cost. The degraded toner is processed based on the detected information, so that the waste toner can be reduced and a good image can be obtained. An image density of an image that is transferred with a predetermined reference electric field is detected in a first detecting step. An image density of an image that is transferred with an electric field that is smaller or greater than the reference electric field is detected in a second detecting step. A processing step of processing the degraded toner is performed on the basis of the image density detected by each of the detecting steps. |
