developers and development.

摘要

Disclosed is a two-component type developer comprising a toner having an electroconductivity lower than 3.5 x 10-10 S/cm, in which an amino group-containing silicone resin is used as the coating resin for a magnetic carrier. By using the amino group-containing silicone resin as the coating resin for the magnetic carrier, reduction of the image density caused by a lowly electroconductive toner is prevented, and even in a color developer for which a lowly electroconductive toner is used, a high-density image can be formed. According to a developing process using this developer, the development is possible even under a high bias voltage condition, and a high-quality image having a high density can be formed.
