description	PROBLEM TO BE SOLVED: To implement an apparatus which prolongs the lifetime of a developer material and has sufficient reload and less mottle to provide a high printing image quality and allows high-speed printing which the markets demand. SOLUTION: In order to transport toner to a movable photoconductive belt 110, rotatable donor rolls 12 122 (and 124) constituting a developer unit are loaded with the toner, by a loading apparatus, comprising a reservoir for the developer material and a plurality of rotatable rolls, which are provided in a housing. A trim roll 112 from among the rotatable rolls picks up the developer material in the reservoir and hands off the developer material to a first magnetic brush roll (mag roll) 114. The first mag roll 114 delivers the toner in the developer material to the first donor roll 122 and delivers the developer material to a second mag roller 116. The second mag roller 116, of which the axis of rotation is positioned below that of the first mag roll 114, delivers the toner in the developer material to the first donor roll 122.
