AbstractThis specification discloses a method of toner transfer development in which one-component magnetic developer is conveyed to a developing position by the action of a magnetic field and a low frequency alternating electrical bias is applied to the space between a latent image bearing member and a developer carrying member at that position to thereby develop a latent image. This development provides visible images excellent in sharpness and tone reproduction.
