1. An image forming apparatus, comprising:
a developing device which develops an electrostatic latent image formed on an image bearing member using toner and magnetic carrier; a toner supplying device which supplies toner from a toner bottle storing toner for supply; a toner density detecting unit which detects information about a toner density inside of the developing device; a control unit which is able to perform a normal mode which determines a toner supply amount of the toner supplying device based on a detection result of the toner density detecting unit and a predetermined target value; a remaining amount detecting unit which detects information relating to a remaining amount of the toner bottle; and a replacement detecting unit which detects information for determining whether the toner bottle is to be replaced, wherein the control unit prohibits an image forming operation based on a detection result of the remaining amount detecting unit, thereafter the control unit immediately allows the image forming operation based on a detection result of the replacement detecting unit, and the control unit performs a supply restriction mode which restricts the toner supply amount such that the toner supply amount in a predetermined initial period after allowance of the image forming is smaller than the normal mode in a case where a detection result of the toner density detecting unit and the target value are under same conditions, respectively. |
