Abstract:
A developing method for developing an electrostatic latent image formed on an image support, by an inversion development characterized in setting the following relationship:abs(V1)<abs(Vth) where abs (X) represents an absolute value of X, whenV1=(0.348 Wr2âˆ’1.161 Wr+1.0163)Vo, andWr=(1/3.63)Â·(RsÂ·Cp/t)Â½Â·W, whereCp (F/m2) represents an electrostatic capacity of an image support, Rs (&OHgr;) represents a surface resistance, t (sec) represents a moving time from an electrostatic latent image formation area to a development completion area, Vo (V) represents a potential of a non-image portion of an electrostatic latent image in an image area at the time of forming the electrostatic latent image, Vth (V) represents a surface voltage of the image support when a developing member starts a development at a saturated latent image potential in a solid image, W (m) represents a desired minimum image width, and V1 (V) represents a marginal latent image potential in the minimum image width.
