Abstract:
A method comprisingmoving a surface of a developer-bearing member and a surface of an electrostatic latent-image-bearing member at different velocities to develop one or more electrostatic latent images with a developer, wherein said electrostatic image bearing member is configured to face said developer-bearing member, wherein a developer comprising a magnetic carrier and a toner is presented one said surface of said developer-bearing member, and wherein said development is carried out under conditions represented by formula (1): 0.1&it;â€ƒ&it;mm&leq;k=L&CenterDot;[(Vr/Vp)-1]&leq;2&it;â€ƒ&it;mm(1)wherein Vp is a transporting velocity (mm/sec) of said surface of said electrostatic-latent-image-bearing member, Vr is a transporting velocity (mm/sec) of said surface of said developer-bearing member and L is a width (mm) of acontact portion between said developer and said electrostatic-latent-image-bearing member.
