Abstract: An image forming method using a cleaning blade which prevents the spherical toner to pass through a gap between the blade and a photosensitive member and which has durability so as to be less worn away or chipped, wherein it is possible to maintain cleaning performance over a long term even in high-speed printing using spherical toner, and a non-transferred toner and external additives dropping out from colored particles less causes filming on the photosensitive member and less gives damage to the surface of the photosensitive member, is provided. A method of forming an image using a toner having an average circularity of 0.95 to 0.998 to perform developing, transferring, fixing and cleaning for removing the toner remaining on the photosensitive member after the transferring by a cleaning blade 6 abutting on the photosensitive member, wherein an abutting portion of the cleaning blade 6 on the photosensitive member has an indentation modulus (A) of 5 to 15 KPa at an indenting load of 10 mN and 23° C.

Abstract: A toner for an image-forming apparatus and method which apparatus has a cleaning means with a cleaning blade to remove a residual toner remaining on a surface of a photoconductive member after transfer; the toner being a mixture of a colored polymer particle and an external additive. The colored polymer particle has an average circle degree in the range of 0.95-0.995 and a volume average particle diameter in the range of 3-8 ?m. The toner has an absolute value of charge amount in the range of 20-70 ?C/g in a toner layer formed on a developing roll when the toner is used with the image-forming apparatus.

Abstract: The present invention is to provide a method of producing a non-magnetic one-component toner for developing an electrostatic image which is well-balanced between shelf stability and fixing ability at low temperature and has a good charge property so that printing performance is excellent from the viewpoint of hardly producing printing soiling such as fogs or the like.

Abstract: The present invention aims to provide a non-magnetic toner for developing electrostatic image which is able to perform stable high-quality printing in spite of environmental changes in, for example, temperature, humidity and so on. The non-magnetic toner for developing electrostatic image comprising a colored particle, produced by a method comprising a step of forming a droplet in an aqueous dispersion medium containing a dispersion stabilizer, wherein a volume average particle diameter of the toner for developing electrostatic image is from 3 to 10 ?m and an amount of adsorbed moisture of the non-magnetic toner for developing electrostatic image at 32° C. and a relative humidity of 80% is from 0.1 to 0.25 wt %.
