I keep needing to clean the sensor on my camera. Literally after every two or three shoots. I do change lens but I try to limit this to one change per shoot. I usually try to change lens in a 'clean room' - my bathroom if I'm at home. If on a shoot I do it very quickly in the most dust free area I can find with the camera facing downwards.
l be really grateful for any advice. How often do people need to clean the sensor? Is this unusual?
I don't think many photographers worry about changing in a "clean room" or limiting lens changes to one per shoot. Just how bad is the dust? Can you post an image that shows the extent of it? What camera do you have?
Dust is something you have to deal with. You'll get dust if you never change the lens. A few specks can be cloned out easily.
Is the camera or the lens new ? Often with either a new camera or a new lens on an already seasoned camera you might get some specks, dust, flakes, grease tiny blobs... After a while, using one or another, it's replaced by good old dust
Unless shooting regularly at f/16, the two or three usual dust specks tend to go away easily with a blower and don't need servicing every two or three shoots. I give my sensor to clean twice a year and in the meantime if I have some troublesome specks I use the blower !
I usually use prime lenses and change them when needed, on location, keeping the camera looking down and not in the wind bed, but otherwise don't stress too much about it. But I do get my lenses cleaned at least once a year...!

You mentioned that your camera is new. Does it have a self cleaning sensor mode? If so have you turned it on? I have my D4 set to run the clean mode when turning the camera off and have had no spots show up at all. Your sample looks like a smear, but maybe one from a incomplete cleaning with a swab, just a guess though.
It's a funny thing - I shoot a D2Xs and quite often use primes - I carry 3 and regularly change when out and about... I hardly ever suffer from dust spots and if I do it is just a couple of blows with a blower brush and they are gone...
Yours look like smears as has been said... maybe time for a sensor clean. If the camera is brand new maybe a visit to the place of purchase for a check?
If you check your sensor for dust every day at f/22 you'll find dust evey day. If you blow it clean on a semi-regular basis and do a serious clean when you notice dust in photographs, then you'll clean it every few months or years.
I've changed lenses in Kuwaiti dust storms. It was a good way to teach myself the importance of protecting the sensor (not important) compared to getting the shot (huge importance).
I think basic cleaning with a blower is going to be pretty common. I would expect daily cleaning or certainly every few shoots depending on conditions. And don't forget to blow out the mirror box - not just the sensor.
The D3x is a dust magnet.I have to dry clean it almost every day in shooting situation.This spec look like a lube spot of some sort that was drag over the sensor by a dry cleaning effort.A wet clean up will probably take care of this bummer. So far for my D4 ( 5000 clics) no specs at all...WOW !
I have over 4,000 clicks on my d4 and have blown out the sensor with a hand blower a couple times and then tested shooting a blue sky at an f16 f stop, result no dust bunnies. Make sure that you have turned on the sensor shaker to come on when you turn on and off the camera. I do agree with other replies that it looks more like a smear than dust bunnies. If not removable by blower, then need to wet clean by someone or yourself. The d4 is not a dust attracter.
