摘要：
A developing device configured such that an amount of weakly charged toner in a two-component developer passing through an opening in the device per unit time is not greater than 200 g·mm/min, wherein the amount of weakly charged toner is expressed by an equation, which is the amount of weakly charged toner [ g · mm / min ] = total amount of the two - component developer to be drawn [ g / min ] × length of the opening [ mm ] × a concentration of toner [ wt % ] × percentage of weakly charged toner [ % ] .
