Electrostatic latent image developing device for monocomponent toner comprising plural toner transport members with different electroconductivity

摘要

A developing device developes an electrostatic latent image formed on a rotatable electrostatic latent image support member. The developing device includes a rotatable first toner transport member in contact with an electrostatic latent image support member and a rotatable second toner transport member in contact with an electrostatic latent image support member. Toner layers are formed on the peripheral surface of the first toner transport member and the second toner transport member. The electric conductivity of the first toner transport member is different from that of the second toner transport member.
