where is the rust forming? if it is on the main face of the rotor its ok, you may not have driven the car for a little while after a wash or from the rain and it has just rusted. just drive around and apply the brakes like normal and it will get rid of the rust
unforuntately if it like a ring around where the hub and the brake pad does not reach it then im afraid there is not much you can do about it unless you want to pain your hub with a colour so that rust does not form there anymore due to the paint.
