Abstract
The present invention provides a toner for electrostatic latent image development and a method of magnetic monocomponent development using the toner which can prevent the toner adhesion to a photoconductor for a long time period and can obtain an image having high quality by maintaining functions of the toner for a long time period or by favorably adjusting the conveying property of the toner on a developing sleeve. In a toner for electrostatic latent image development which contains toner particles and inorganic particles and a method of development using the toner, the toner particles exhibit a shape factor SF-1 which satisfies the relationship 115≦SF-1≦150 and a shape factor SF-2 which satisfies the relationship 115≦SF-2≦145 and, at the same time, a quantity of inorganic particles which are in a floating state is set to a value which falls within a range from 10 weight % to 25 weight % with respect to the total quantity of the inorganic particles.
