Abstract

In order to control development condition and/or transfer condition for stable image forming, toner patterns of the same density are formed on a photoconductor and are transferred onto a paper or the like while changing the transfer current. Then, the transfer efficiencies of the toner patterns are measured. Other characteristics such as the resistance of the paper and charge of toners may also be monitored. Then, the development condition and/or transfer condition is controlled according to the detected data.
