摘要：
A toner sensor measures the amount of toner attached onto a photosensitive drum upon development by a developing unit. A controller compares the measured toner attaching amount with a predetermined reference value, and executes processing for changing at least one of image forming conditions, for example, the charging amount by a charger, the developing bias voltage of the developing unit, the exposure amount of an optical system, and the toner density of the developing unit, on the basis of the comparison result.
