Abstract:
A developing agent storage device for storing a refill developing agent includes toner particles, carrier particles, an inner layer of the developing agent storage device. The toner particles and carrier particles compose the refill developing agent. The inner layer is provided as a wall contacting the refill developing agent. An electrostatic chargeability level of the toner particles, the carrier particles, and the inner layer is set in an order of toner, inner layer, and carrier from any one of a negative charge side and a positive charge side.
