<p>PROBLEM TO BE SOLVED: To provide a magnetic one component developer which is useful as a developer to be used for an electrophotographic device, which has both of a property for preventing a development ghost and transfer characteristics in a high level, which gives picture quality at a high level without causing a development ghost, decrease in image density or irregularity in image density even when the toner is used under a high temperature and high humidity environment or a low temperature and low humidity environment. SOLUTION: The magnetic single component developer consists of toner particles containing binder resin and magnetic material and external additives. The external additives contain magnetic powder having 102 to 106Ω.cm volume resistivity.</p> |
