Abstract
PURPOSE: To provide a static charge image developer having improved developing efficiency and preventing an image quality deterioration without using a carrier by composing a toner essentially of resin and a ferromagnetic material and forming the toner into spheres having frictional chargeability.
CONSTITUTION: A thermoplastic resin such as styrene resin giving insulating properties as essential component of a toner, a colorant such as carbon black and a ferromagnetic body of fine particle form are blended, if necessary, dye, pigment, a charge controlling agent, etc. may be added. They are mixed, dispersed, kneaded, cooled, and pulverized. The surface of toner particles is sphered by spraying into hot air or other method. This toner has high frictional chargeability and fluidity. Using a static charge image developer contg. this insulating magnetic toner alone as a essential component, a fine transfer image is obtd. with a simple device.
