ABSTRACT:
A developer roller (5) is rotated rapidly for high speed printing, which can cause excessive heating at end seal (1). Heat damage to toner (24) is avoided by providing gaps (30a,30b) under the seals (1) which reduce the stiffness of developer roller (5) and thereby reduce frictional heating.
