Abstract

An image forming apparatus comprises an image carrying body, a developing unit, a developer container, a developer supplying unit, a developer transport passage filling unit, a control unit, and a display unit, wherein the control unit calculates a remaining toner ratio based on an operation amount of the developer supplying unit, the control unit performs an operation of controlling the display unit to display the remaining quantity of the developer in the developer container, based on the remaining toner ratio, and the control unit performs an operation of controlling the display unit forcibly to display information indicating that the developer container is full regardless of the remaining toner ratio, when the developer transport passage filling unit fills the developer transport passage with the developer supplied from the developer container at the predetermined time.

Description

[0001] This application is a divisional application of an invention patent application filed on October 18, 2007, with the title of invention "Chroma Dose Display System, Image Forming Device and System, and Information Processing Method" and application number 200710151449.8. technical field [0002] The present invention relates to an image forming apparatus. Background technique [0003] Conventionally, as an example of an image forming apparatus such as a laser printer and an inkjet printer, there is known an image forming apparatus in which a color developer such as toner or ink is contained in a container that It is detachably installed in the image forming apparatus, and when the developer contained in the currently installed container is used up, the container can be replaced with a new one. For example, see the following patent documents: [0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2002-357945 [0005] [Patent Document 2] Ja...
