Claim Text:
1. A multi-function image forming apparatus having multiple image forming functions and operable with a battery, comprising: a voltage detector to detect voltage drop in battery output when the image forming apparatus enters an operating mode amongst plural candidate operating modes of different corresponding image forming functions; a memory to store, for each candidate mode amongst the plural candidate operating modes of corresponding image forming functions, predetermined voltage drop data associating the candidate mode with the voltage drop in battery output in performing the image forming function of the candidate mode; a battery power detector to detect charge remaining on the battery; and an operating mode determination unit to determine whether or not the operating mode is executable based on the detected charge remaining in the battery, wherein the operating mode determination unit compares the detected charge to a predetermined value, and if the detected charge is not lower than the predetermined value, the operating mode determination unit determines that the operating mode is executable, and if the detected charge is lower than the predetermined value, the operating mode determination unit references the predetermined voltage drop data associating the operating mode with the voltage drop in battery output in performing the image forming function of the operating mode to determine whether the operating mode is executable.
