ABSTRACT:
The present invention relates to a non-magnetic one-component toner that is characterized by containing toner particles that have a volume-average particle size of 2 to 8 μm, a ratio of the volume-average particle size
umber-average particle size of not more than 1.22, an average degree of roundness of not less than 0.92 and a Vickers hardness of not less than 13.5HV0.01 (10 g), and also concerns a non-magnetic one-component contact developing device using such a toner and an image-forming apparatus using such a developing device.
