An image forming apparatus includes a display unit, an operation unit, a memory, and a control unit. The operation unit is operable by a user. The memory stores log information. The control unit includes a processor and, based on operation of the processor in accordance with an operation control program, allows, at an occurrence of an error, the display unit to display an error code correspondingto the error, and upon acceptance of input of a maintenance mode activation password inputted by operating the operation unit, activates a maintenance mode. Under an activation state of the maintenance mode, the control unit reads out the log information from the memory and saves the log information onto a predetermined recording medium, and allows the display unit to display a maintenance screenafter the saving of the log information. Therefore, when the maintenance mode of the image forming apparatus is set, the disappearance of the log information due to operation for maintenance can be prevented.
