摘要:
A developing apparatus characterized in being constituted to satisfy Equation (1) shown below when an amount of a developer carried by 1 pitch of a carrying member of an auger or the like is designated by notation W(g), a toner amount supplied by 1 pitch during a time period in which the developer carried by 1 pitch passes a supply region of a toner supply roller is designated by notation M(g), a toner concentration of the developer detected by a toner concentration sensor is designated by notation Tc (%), and a mixing limit toner concentration is designated by notation Tmax (%). (W×(Tc/100)+M)/(W+M)≦Tmax/100 (1)
