A reformer is someone who works to make a social or political system better — schools, prisons, land laws, voting — by changing the rules and the habits, not by throwing the whole system away. History books speak of prison reformers and education reformers; the Protestant Reformers of the 1500s are a famous, often capital-R group of this kind.
