Depends on how careful you are when you're changing lenses. But sometimes cameras come from the factory with dust on the sensor. And it's not like camera bodies are hermetically sealed, after all.

Get a RocketBlower. Use the manual sensor cleaning mode, and holding the camera face down, puff some air at the sensor (taking care to keep the tip from touching anything). Wait a second or two for the dust to "float" out and settle. Turn the camera off.

See if that helps before going the contact-cleaning routes. As long as the dust was dry when it hit the sensor, it should come off relatively easily. If it's the welded-on-while-wet kind, you may need to use a contact-cleaning method, then. A lot of folks will tell you about pecpads and cleaning fluids, but you may also want to consider the sensorklear lenspen.
