Image forming device having division management function

A method of managing an image forming device, comprising:

• accepting a request for image forming in a color mode or a request for image forming in monochromatic mode;
• identifying a division to which a user belongs who has requested the accepted image forming;
• executing the image forming in the monochromatic mode for a job requiring the monochromatic mode without identifying the division, in a case where a division management function which manages the number of pages having an image formed thereon for each division is valid and a color management function which manages the number of pages having an image formed thereon in the color mode is valid,
• executing the image forming in the color mode and monochromatic mode in the image forming unit if the division to which the user belongs is identified by the identification unit, in a case where the division management function is valid and the color management function is not valid, and
• counting the number of pages having the image formed thereon in the color mode for each identified division, in a case where the division management function is valid and the color management function is valid.

An image forming device comprising:

• image forming means for forming a color image on an image forming medium if an operation mode is a color mode, and for forming a monochromatic image on the image forming medium if the operation mode is a monochromatic mode;
• identification means for identifying a division to which a user belongs who has requested image forming;
• division management means for managing the number of pages having the image formed thereon for each division identified by the identification means;
• color management means for managing the number of pages having the image formed thereon in the color mode;
• and
• control means for executing the image forming in the monochromatic mode for a job requiring the monochromatic mode in the image forming means without identifying the division by the identification means, in a case where the division management means and the color management means are valid,
• the control means executing the image forming the color mode in the image forming means, if the division to which the user belongs is identified by the identification means, in a case where the division management means and the color management means are valid, and the control means executing the image forming in the color mode and the monochromatic mode in the image forming means if the division to which the user belongs is identified by the identification means, in a case where the division management means is valid and the color management means is not valid.
