Abstract
A toner cartridge with a handle formed centrally in a trailing end of the cartridge. The handle is dished to comfortably accept a hand and is adapted such that a user will recognize that said handle is dedicated to receiving the user's hand. The cartridge is therefore installed and removed without binding since the user's hand is centered as a result of the placement of the user's hand in said handle.
