A toner for hybrid development, comprising toner particles containing at
least a binder resin and a colorant and being charged when made in
friction-contact with a carrier; reverse polarity particles that are
charged to polarity reversed to the charged polarity of the toner
particles when made in friction-contact with the carrier, and have a
number-average primary particle size in a range from 95 to 850 nm; and
same polarity particles that are charged into the same polarity as the
charged polarity of the toner particles when made in friction-contact
with the carrier, and have a number-average primary particle size in a
range from 80 to 800 nm and a shape factor in a range from 100 to 160; a
developer for hybrid development containing the above toner and a
carrier; and an image-forming apparatus provided with the developer for
hybrid development.
