Abstract
In the development system of an electrophotographic apparatus, a selected ratio of electrostatic charge per unit mass for particles adhering to a member transporting to a surface having a latent image recorded thereon is maintained. Means are provided for controlling a ratio of particle mass to the member surface area, and such means are controlled as a function of the selected ratio of electrostatic charge to unit mass to regulate the ratio of particle mass to the member surface area so as to substantially maintain particle electrostatic charge to unit mass ratio at the selected ratio of electrostatic charge to unit mass.

An apparatus for maintaining a selected ratio of electrostatic charge per unit mass for particles adhering to a member transporting to a surface having a latent image recorded thereon, comprising:
- means for controlling a ratio of particle mass to the member surface area;
- and
- means for adjusting the controlling means as a function of the selected ratio of electrostatic charge to unit mass to regulate the ratio of particle mass to the member surface area so as to substantially maintain particle electrostatic charge to unit mass ratio at the selected ratio of electrostatic charge to unit mass.
A method for maintaining a selected ratio of electrostatic charge per unit mass for particles adhering to a member transporting to a surface having a latent image recorded thereon, comprising the steps of:
- controlling a ratio of particle mass to the member surface area;
- and
- adjusting the ratio of particle mass to the member surface area as a function of the selected ratio of electrostatic charge to unit mass to regulate the ratio of particle mass to the member surface area so as to substantially maintain particle electrostatic charge to unit mass ratio at the selected ratio of electrostatic charge to unit mass.
