ABSTRACT:
Disclosed is a two-component type developer comprising a toner and a coated magnetic carrier wherein said toner has an electroconductivity lower than 3.5.times.10.sup.-10 S/cm and the coating of said magnetic carrier consists of a silicone resin having as its component unit a basic nitrogen atom-containing organic group bonded to a silicone atom (N-containing silicone resin).
Such developer is capable of forming images having a high image density and a high image quality, particularly as a white developer or a color developer if developing is carried out even under ordinary conditions, since the toner has its charge quantity maintained in an appropriate range in the developing step.
