摘要：
A target specified range of a toner density is correctly set so that a toner density is consistently appropriately controlled.If a specified range within which a measured toner density TD (%) should fall is set based on an expression (2) below using a volume average diameter Dcav_vol (μm) of a magnetic carrier and a volume average diameter Dtav_vol (μm) of a toner, the target specified range can be correctly set, thereby making it possible to consistently appropriately control the toner density. TD≦{γt·Vt/Nt/(γc·Vc)}×100 (2)
