<p>PROBLEM TO BE SOLVED: To provide a toner excellent in flowability, hardly affected by an ambient condition such as a temperature and humidity, restrained in generation of deposit on a photoreceptor surface, and having stable frictional chargeability. SOLUTION: In this toner having toner particles containing at least a binder resin and a coloring agent and alumina fine particulates, the alumina fine particulates contains 200-700μg of zirconium per 1 g of the alumina fine particulates. The toner has a very stable circumstantial characteristic, superior flowability and transfer property, and polishing ability for a photoreceptor surface and deposit, so as to provide a highly fine image of high quality, which is very stable under circumstances such as a high temperature and high humidity, or a low temperature and low humidity.</p> |
