1. An image forming device comprising:
an image forming unit configured to form an image on a sheet based on image data; a holding section to which either a first developer cartridge or a second developer cartridge is attachable, each of the first developer cartridge and the second developer cartridge being configured to accommodate developer therein, the second developer cartridge having capacity for accommodating developer larger than capacity for accommodating developer of the first developer cartridge; a detection device configured to detect a remaining amount of developer in a developer cartridge attached to the holding section and configured to output detection information; and a control device configured to control the image forming unit to form the image on the sheet when the image data is inputted, wherein the control device is further configured to:
determine whether the developer cartridge attached to the holding section is the first developer cartridge or the second developer cartridge;determine that replacement of the developer cartridge attached to the holding section is needed upon comparison of a consumed amount of developer based on the image data that is inputted with a first prescribed threshold value when the developer cartridge attached to the holding section is determined to be the first developer cartridge; anddetermine that replacement of the developer cartridge attached to the holding section is needed upon comparison of a detection value with a second prescribed threshold value when the developer cartridge attached to the holding section is determined to be the second developer cartridge, the detection value being based on the detection information outputted by the detection device. |
