1. An image forming apparatus for forming an image on a recording medium based on image data to output the recording medium on which the image is formed, comprising:
a tray on which a recording medium having an unfixed form size can be stacked;
a size detecting section to detect a size of a recording medium stacked on the tray;
an information retaining section to register the size of the recording medium having the unfixed form size therein;
a setting section to set the tray as either a fixed-form size tray or an unfixed-form size tray;
a display section to display unfixed form sizes registered in advance in the information retaining section; and
a controller to acquire an approximate size of the recording medium having the unfixed form size by referring to information in regard to the size detected by the size detecting section, when the recording medium having the unfixed form size is stacked on the tray, which is currently set as the unfixed-form size tray;
wherein based on the approximate size, the controller controls the display section to display the unfixed form sizes registered in the information retaining section, in such a manner that the unfixed form sizes are displayed on a screen in order of size largeness while setting a size nearest to the approximate size at first, as choices for a user.
