A person who is devoted to or practices grangerism.
From 'Granger' + '-ite' (follower or devotee suffix, as in 'Jacobite' or 'Methodist'). Creates a term for someone deeply committed to the practice.
The suffix '-ite' was used to describe dedicated followers of a practice or belief, so 'grangerites' were genuine enthusiasts—fanatics even—of illustration collecting!
