Voltage regulator inside the alternator is probably burned up or on the way out. Replacing the entire alternator is the way to fix it. With a Toyota one might I add, dont cheap out on a chain autoparts store one.

Double check you voltage readings, you are using a multimeter on the battery post to check correct?
