An objective is to provide an electrostatic latent image developing toner exhibiting ultra-low temperature fixability together with high resolution, excellent fluidity and anti-blocking property, and excellent aging stability in a toner vessel, in which the toner is supplied into an image forming apparatus. Also disclosed is an electrostatic latent image developing toner stored in a vessel possessing an ejecting outlet, capable of fitting into an image forming apparatus, wherein the vessel has a cross-sectional area of the outlet of 0.07-2.00 cm.sup.2; the toner possesses a resin, a colorant and an external additive; the toner has a Tg of 16-44.degree. C.; an X-ray intensity ratio of Ti/Si via fluorescent X-ray analysis of toner, is 1.0-2.5; and toner particles, and having a ratio of 2.sup.nd short axis to 1.sup.st short axis being 1.1-1.6 have an amount of 5-50% in terms of the number of particles.
