<p>PURPOSE:To obtain such a toner that reduction in fluidity after long-term running is not caused, and the production of filming, fog, the reduction of image density, scratches on a photosensitive body or white dot in a solid image are prevented, and to obtain an image forming method having a toner recycling process by which a reduction in fluidity after long-term running is not caused, and the production of filming, fog, a reduction in image density, scratches on a photosensitive body or white dot in solid image are prevented. CONSTITUTION:The toner contains color particles comprising at least a resin and a coloring agent and inorg. fine particles having 5-50nm number average primary particle size and is mixed with a carrier to constitute a two-component developer. In this toner, the amt. of aggregates of inorg. particles separated from the toner and having >=47mum size is <=0.05wt.% of the toner weight with addition of inorg. fine particles, the amt. of aggregates having the size between >=20mum and <47mum is 0.01-0.1wt.%, and the amt. of aggregates having the size between >=2mum and <20mum is <=1.0 number %.</p> |
