Not bent.

The forward sweep of the bottom of the fork puts the angle of the fork at the top of the tire in the relative angle to make it look like the fork is bent. If you put a straight edge along the head tube in the picture (like I just did on the computer screen), there is, if anything, a slight forward angle to the fork.

Cameras have a way of making a fork look bent. Part of it is that in a flat projection the eye looks at the wrong visual cues to determine whether the fork is straight or not. In real life, your eye tends to focus on the line down the head tube; in pics it tends to focus on the spot where the fork crosses the tire, and if there is any rake at all on the fork it gives the illusion of a bent fork.
