Provided is a replenisher developer cartridge for a trickle developing system image forming apparatus producing no image problem such as image density unevenness, image roughness or the like. Not only an image forming apparatus by which high quality images are stably output, and a replenisher developer cartridge for the image forming apparatus were possible to be provided, but also durability of a two-component developer used in the image forming apparatus was possible to be improved, by replenishing the image forming apparatus with a replenisher developer in the carrier concentration range of 5-30% by weight in terms of the mean value, and in the carrier concentration deviation range of 10% by weight or less, based on the replenisher developer.
