    摘要: A toner is provided for electrostatic latent image developing which exhibits desirable smearing, offset and filming characteristics during copying, and which has excellent toner flow characteristics and chargeability properties. The toner of the present invention contains at least a binder resin containing polyethylene wax, and at least polypropylene wax, and colorant. The toner of the present invention is made by a process whereby polyethylene wax is added to a binder resin to form a mixture. The mixture is then added or mixed with a colorant and polypropylene wax.

    摘要: An image forming apparatus is provided which includes an image bearer, a charger, an irradiator, a developing device to develop an electrostatic latent image on the image bearer with a toner to form a toner image, a transfer device to transfer the toner image onto a transfer medium, and a cleaner to remove toner particles remaining on the image bearer without being transferred. The toner includes a mother particle including a binder resin and a colorant and one or more external additives. At least one of the external additives includes primary particles having a number average particle diameter in the range of 0.05 to 0.30 μm. The cleaner includes an elastic body blade having a contact part with the image bearer. The contact part has a surface elastic modulus in the range of 15 to 25 N/mm2 and a surface friction coefficient in the range of 0.5 to 0.7.
