Will putting a fan near my heater help disperse heat throughout my apartment quicker?

Consider someone peeing in a pool. If the water is still the heat from the pee will for the most part be localized and only slowly spread. Introduce some waves and the heat will be dispersed more evenly throughout the pool.
(sorry for the gross example, but I think it works as an analogy.)
Also see Number 5 in the second source. It talks about using fans with air conditioning but the principles are the same.

The government has performed energy savings experiments in the past, to study downdraft fans that circulate hot air from heating sources down from near the ceiling towards the ground -- it has been shown that such things are only cost effective and worthwhile if the building itself is thermally very leaky to begin with, and those fans are low speed to begin with.

The rate at which your heater transfers heat into the surrounding air is dependant upon the temperature difference between the heater and the surrounding air. Therefore, stagnant air will heat up and slow the heat transfer. Having air constantly circulating across the surface of the heater will make it more efficient.
Also the more air flow you have, the better dispersed the heat will be across your apartment.
For example, most space heaters have fans on them for efficient evenly dispersed heat.
However, how much good it will do depends on on the size of the fan, the size of your apartment, and the power of your heater.

M$If it's the kind with a hot quartz element and a polished reflector, then no-- the heat is sent out as infrared rays and the fan can't interact with them.
If it's a wall-mounted gas heater it sends its heat out by convection, where it rises and hopefully spreads out along the ceiling. A fan at ground level is not going to do much.
If it's an electric space heater, most of these already have fans and extra fans might help a little bit.

M$Look at Wikipedia under Convection and you will find a heading for Forced Convection which covers natural heat convection or free convection.
This will explain just how heat is transferred and provides some good examples.
In short, it will depend on the size of your apartment and the heat and air source. The larger the apartment and number of rooms, the more heat and air mass needed to carry it.
Understanding that you will find that it will work.
Good luck!

if you have ceiling fans, run them, at their slowest speed, and remember to reverse the direction. (so the air "blows" towarsd the ceiling.)

Long answer
It isn't air that is heating up believe it or not its heat reflection from its heat sink source (fins usually) that disperse heat threwout your home.
Forcing air from one place to another via a fan|heater type setup wont work unless you have ducts under your home moving said air.
Also the air would be moving in a central location against or in front of your heater , it would be moving to fast to have any affect.
