Abstract:
An image forming apparatus at least containing an electrophotographic photoconductor, a latent electrostatic image forming unit, a developing unit, a transferring unit, and a fixing unit, wherein a glass transition temperature of an outermost layer of the electrophotographic photoconductor is 100° C. or more, wherein the toner is obtained by dissolving and/or dispersing the toner material containing at least an active hydrogen group-containing compound and a polymer reactive with the active hydrogen group-containing compound in an organic solvent to form a solution and/or a dispersion, emulsifying and/or dispersing the solution and/or the dispersion in an aqueous medium containing resin fine particles, allowing the active hydrogen group-containing compound and the polymer reactive with the active hydrogen group-containing compound to react in the aqueous medium, and removing the organic solvent, wherein a glass transition temperature of the resin fine particles is 65° C. to 85° C.
