IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To efficiently consume a deteriorated toner inside a developing device through toner forcible consumption control while suppressing adhesion of a carrier.SOLUTION: A control part starts toner forcible consumption control of causing a toner in a developing case to be adhered to a latent image carrier to forcibly consume the toner in the developing case at a predetermined toner forcible consumption timing while stopping supply of toner by toner supply means, terminates the toner forcible consumption control when the toner density of the developer inside the developing case reaches a normal toner density that has been set lower than a target toner density on the basis of a result of the detection by toner density detection means, and subsequently executes post-toner forcible consumption toner supply control of controlling the toner supply means to supply a toner to the developing case.SELECTED DRAWING: Figure 1
