Abstract

PURPOSE:To enhance hiding power of a toner by dispersing a rutile type titanium oxide specified in the particle diameter range into a resin having a refractive index of a prescribed value or less. CONSTITUTION:The white toner is produced by dispersing the rutile type titanium oxide having a particle diameter of 0.1-0.2mum into the fixing resin medium having a refractive index of <=1.50, such as polymethyl methacrylate, and if the particle diameter is less than said range, light reflection and refraction become difficult to occur and said hiding power is weakened, and if it is over the range, dispersibility is deteriorated and the drum surface of the photosensitive body becomes easily scratchable, and an offset preventive, a pressure fixability imparting agent, and a positive or negative charge controller or the like may be added when needed.
