When two egg cells are fertilized by two sperm cells in the same period of time, fraternal twins are formed. So, if a woman’s ovaries release more than one egg during ovulation and the woman has contact with more than one man during her fertile period, it is possible that she will become pregnant with twins who have different fathers. This phenomenon is extremely rare, but possible.
In even rarer cases, fraternal twins from different fathers may result from mistakes made during assisted fertility procedures. For instance, if a woman is artificially inseminated with a mixture of two men’s sperm cells because the equipment was not properly cleaned after its last use, she may become pregnant with fraternal twins who have different biological fathers. Again, while possible, this occurrence is exceedingly rare.
Note: Identical twins cannot have different fathers. Identical twins are formed when the zygote created from one egg cell and one sperm cell splits during its development. When a single zygote produces twins, one man is the father of both children.

VERY UNLIKELY!
I agree with Robbet, but the chances that the sperm from the first donor would not fertilize the second egg is highly unlikely. The probablility for 2 fathers would increase if the sperm from both fathers were somehow mixed prior to vaginal insertion, but then there's the possibility that the sperm from both donors would die if not inserted immediately. Another scenario would be in-vitro fertilization where the 2 eggs were synthetically fertilized separately in a controlled environment and then introduced to the mother.
More than likely, the twins are by the same father unless there was an in-vitro or sperm mixing situation.

Normally when a woman ovulates, her body releases one egg to be fertalized. Sometimes two eggs are released. If both these eggs are fertalized by a sperm and develop into babies you will have faternal twins, or non-identical twins (such as twins that are one boy and one girl). If a woman release two eggs and had sex with two different men within a close enough time frame, it would be possible for one man's sperm to fertalize one egg and the sperm from the other man to fertalize the second egg.

I have heard of cases where this is possible, but like you said, only in fraternal not identical.
