Abstract
A developing apparatus for developing an electrostatic latent image includes a container for containing a one component developer; a rotatable developer carrying member for carrying the one component developer and for supplying the developer to an electrostatic latent image bearing member; and a rotatable elastic roller, rotatable in contact with the developer carrying member, for applying the one component developer contained in the container to the developer carrying member; wherein an elastic layer of the elastic roller in contact with the developer carrying member is composed of a closed-cell foamed rubber, and has a density of 0.18 g/cm.sup.3 -0.28 g/cm.sup.3.
Claims5
A developing apparatus for developing an electrostatic latent image, comprising:
- a container for containing a one component developer;
