Abstract: Provided is an image forming apparatus to control capturing of an execution screen displayed. A memory stores at least one application. A user interface device displays an execution screen of an application, to which a user is logged in with an identification (ID) of the user, and receives an input of capturing the execution screen. A processor determines an authority of the ID of the user to capture the execution screen by comparing a security level of the execution screen set based on the data displayed on the execution screen and a security level of the user set with respect to the ID of the user. The processor, in response to the input, controls the capturing of the execution screen, based on the determined authority of the ID of the first user.
