A method of controlling image density includes imaging a pattern of reference density as a toner image on a photoconductor. The density of the toner image is detected by a reflection-type photosensor, and parameters on the image density are adjusted based upon the results of this detection. In this invention, prior to measuring the reference density toner image, the drive current for the reflection-type photosensor is varied, and output from the reflection-type photosensor is measured while no toner is present on the photoconductor. A reference value of the drive current for the reflection-type photosensor which permits output from the reflection-type photosensor to be a predetermined value is determined. Then, the drive current for the reflection-type photosensor for measuring the reference density toner image is set based on the reference drive current value.
In a method of controlling image density where a reference density pattern is imaged as a toner image on a photoconductor, a density of the toner image is detected by means of a reflection-type photosensor, and parameters relating to image density are adjusted based upon results of detection by the reflection-type photosensor;
