Metering blade for single-component magnetic developer in a xerographic apparatus
 In a xerographic printer having single-component development, a metering blade that creates a uniform layer of toner on the developer roll is bowed with the ends of the blade curved toward the developer roll. The bowed blade results in more uniform metering pressure across the developer roll.
