I'm not an attorney, so this isn't legal advice, but I wouldn't think so.
He's already evicted you, your credit has already taken the hit of eviction. He can "try" to charge you whatever he likes, but since you've been evicted, I don't see how he can force you to pay. It's up to him to mitigate his damages by finding a new tenant.
If you're concerned, it might be worth a phone consultation with a real estate attorney.
