Even when the toner cartridge is placed in a compacted state due to vibration during transportation or in the case of long-term stationary storage, a fixed amount of toner is smoothly supplied from the cartridge without variation when it is mounted on the actual device. To provide a toner for developing an electrostatic latent image that can be stably conveyed without clogging in a toner conveyance path, can suppress a decrease in image density due to poor toner supply, and can reduce the amount of remaining toner in a cartridge. . The basic fluidity energy amount is 50 mJ or more and 150 mJ or less when measured with a powder rheometer under the condition that the tip flow speed of a rotary blade is 100 mm / sec and the approach angle of the rotary blade is -5 °. Aeration flow rate 80 ml / min Rotor blade tip speed 100 mm / sec Electrostatic latent image with a flow fluid energy amount of 0.5 mJ or more and 15 mJ or less as measured by a powder rheometer under the condition of a rotor blade approach angle of -5 ° Development toner.
