Image forming apparatus capable of suspending image formation of image forming device when access cover is open

An image forming apparatus comprising:

• an image forming device that forms an image formed of a toner on a recording paper sheet;
• a container loading portion capable of being loaded with a plurality of toner containers containing the toner of the same color to be supplied to the image forming device;
• a plurality of toner sensors that detect whether the plurality of respective toner containers loaded into the container loading portion are in an empty state;
• an access cover that makes an opening/closing movement to open or close an interior of the container loading portion in replacing each of the toner containers loaded into the container loading portion;
• an open/close sensor that detects whether the access cover is open or closed;
• and
• a control device that includes a processor and functions as a controller through the processor executing a control program, wherein when, during execution of image formation of the image forming device, the open/close sensor detects that the access cover is open and none of the plurality of toner sensors detects an empty state of the associated toner container, the controller suspends the image formation of the image forming device,
• wherein when, during execution of image formation of the image forming device, the open/close sensor detects that the access cover is open and any of the plurality of toner sensors detects an empty state of the associated toner container, the controller allows the image forming device to continue the image formation.
