摘要： The present invention relates to a developing apparatus using magnetic carrier particles and toner particles under the influence of an alternating current. One embodiment of the present invention includes a developer which is a mixture of toner particles and resin coated magnetic particles. An alternating electric field is formed between a latent image bearing member and developer carrying member to form a toner image corresponding to an electrostatic latent image. An electric resistivity curve of the magnetic particles on a coordinate graph, where the abscissa represents an electric field E (V/cm) applied to the magnetic particles and the ordinate represents an electric resistivity R (ohm-cm) of the magnetic particles, crosses a zone defined by lines, AB, BD, DC and CA, whereA is a point with coordinates (0.2.times.10.sup.3, 10.sup.11);B is a point with coordinates (2.times.10.sup.3, 3.times.10.sup.9);C is a point with coordinates (0.2.times.103, 10.sup.8); andD is a point with coordinates (2.times.10.sup.3, 2.times.10.sup.7).The resistivity R is measured by a sandwich type cell having electrodes with a clearance of 0.4 cm and an electrode area of 4 cm.sup.2, in which 1 kg wt. is applied to one of the electrodes, and a voltage is applied across the electrodes.

摘要： In a developing method, a layer of electrically charged toner particles is formed on a surface of a developer carrying member, and magnetic particles which retain on their surfaces electrically charged toner particles are dispersed on the surface of the developing carrying member. The toner particles and magnetic particles are carried on the developing carrying member to a developing position where a surface of an electrostatic latent image bearing member for bearing an electrostatic latent image is opposed with a clearance to the surface of the developer carrying member. An alternating electric field is formed at the developing position against the electrostatic image and chains of magnetic particles are formed by stationary magnetic field generating apparatus disposed behind the developer carrying member. The latent electrostatic latent image is developed by the charge toner particles on the surface of the developer carrying member and on the surface of the magnetic particles in the clearance under the alternating electric field and the stationary magnetic field.
