The bike is leaning to the right and steering straight because your brain is programed to do what's necessary to keep you from falling over. You're leaning in one direction to counter the bike's tendency to steer in the opposite direction, and thereby steering the course you want and not falling over.
As others and I have said, it's a misalignment or tracking issue. It could be at the front end, rear end, both, and or the wheels. For example you could have a basically aligned frame with a wheel off plumb.
