Image forming apparatus, control method, and control program

An image forming apparatus having a first execution environment and a second execution environment different from the first execution environment, the image forming apparatus comprising:

• a display control unit configured to control displaying of a display screen such that a first application cannot be selected on the display screen and at least one second application can be selected on the display screen, wherein the first application runs on the first execution environment to control a scanner unit or a printer unit provided in the image forming apparatus and the second application is added to the image forming apparatus, in response to a user instruction, to run on the second execution environment;
• and
• a deletion unit configured to delete the second application selected from among the at least one second application displayed on the display screen, in response to an instruction for deleting the second application.

An image forming method for controlling an image forming apparatus having an operating system which provides a first execution environment and a virtual machine which provides a second execution environment which runs on the first execution environment, the image forming method comprising:

• a display control step of controlling displaying of a display screen such that a first application cannot be selected on the display screen and at least one second application can be selected on the display screen, wherein the first application runs on the first execution environment to control a scanner unit or a printer unit provided in the image forming apparatus and the second application is added to the image forming apparatus, in response to a user instruction, to run on the second execution environment;
• and
• a deletion step of deleting one second application selected from among the at least one second application displayed on the display screen, in response to an instruction for deleting the one second application.

An image forming method for controlling an image forming apparatus having a first execution environment and a second execution environment different from the first execution environment, the image forming method comprising:

• and
• a deletion step of deleting the second application selected from among the at least one second application displayed on the display screen, in response to an instruction for deleting the second application.

An image forming apparatus having a first execution environment and a second execution environment different from the first execution environment, the image forming apparatus comprising:

• a display control unit configured to control a display panel to display a deletion screen such that a first application cannot be selected on the deletion screen and at least one second application can be selected on the deletion screen, wherein the first application runs on the first execution environment to control a scanner unit or a printer unit provided in the image forming apparatus and the second application is added to the image forming apparatus, in response to a user instruction, to run on the second execution environment;
• and
• a deletion unit configured to delete the second application selected from among the at least one second application displayed on the deletion screen, in response to an instruction for deleting the second application.
