1. An image forming apparatus comprising:
a printer that prints an image on a recording medium;
a display device;
an operation device; and
a control device including a processor, and configured to act as:
an authentication application device that controls authentication of a user, when the processor executes an authentication application program; and
a normal application device, independent from the authentication application device, when the processor executes a normal application program,
wherein the authentication application device
executes user authentication, when the user logs into the image forming apparatus, and
causes, when permitting the user to log into the image forming apparatus, the display device to display a screen including a first button for utilizing a print function originally installed in the image forming apparatus and a second button for utilizing the normal application device, which is a newly installed function,
wherein the normal application device
decides, upon detecting the second button being pressed through the operation device, whether the logged-in user is authorized to utilize the normal application device, on a basis of logged-in user information indicating the normal application device accessible by the logged-in user,
upon deciding that the logged-in user is authorized to utilize the normal application device, executes the activation of the normal application device, and
upon deciding that the logged-in user is not authorized to utilize the normal application device, does not execute the activation of the normal application device, and
wherein the control device executes, upon detecting the first button being pressed through the operation device, a predetermined process for causing the printer to perform printing.
