<p>PURPOSE:To perform low temp. fixing without any trouble with development due to worn toner or carrier particles by conveying a developer including a toner excelling in low temp. fixation and resistance to offset and a magnetic substance particle carrier put on a developer conveying body with the specified roughness to a development zone and by developing an electrostatic charge image. CONSTITUTION:With the use of block copolymers of crystalline polyester and amorphous vinyl polymers or binder resins including the block copolymers, a toner excelling in low temp. fixation and resistance to offset is obtained. Developing material including the toner and a carrier which magnetic substance particles of 2.5-4.0g/cc apparent specific gravity are covered with a resin to form is put on a developer conveying body 11 of 20-60mum surface roughness and conveyed to a developing zone to develop an electrostatic charge image formed on a latent image bearing member.</p> |
