<p>PURPOSE:To provide an electrostatic latent image developer to be used for an image recording device capable of forming uniform picture, and to provide a developer obtaining high picture quality by making the toner uniform in electrification and fast in the rising of electrification. CONSTITUTION:This developer consists of 10-70 pts.wt. of magnetic toner containing at least magnetic powder and resin, and 30-90 pts.wt. of carrier consisting of transition metal oxide having 30-70mum average particle size. The magnetic toner has 5-10mum average particle size, >=0.4g/cc bulk density, <=20% aggregation degree and >=10<9>OMEGAcm volume resistance for 1kHz AC electric field.</p> |
