The present invention provides an image processing apparatus which improves processing efficiency by allowing display of a message according to a usage status of a user and also has good operability. The image processing apparatus includes a setting section 9a for setting a display form of a message 13c. The user sets a display form, that is, display or nondisplay, display time, a color of a display pane, a shape of the display and a display position of the message 13c, to be more precise, from a setting screen capable of setting each kind of message 13c. In the case where “Nondisplay” is selected in selecting display or nondisplay of the message 13c, no setting thereafter is performed. In the case where “Display” is selected, the setting is performed as to all the items, such as the display time, color of the display pane, shape of the display and display position.
