Abstract
A developing sleeve used in a developing device of an electrophotographic apparatus is composed of a sleeve base and an electrodeposition coating formed on the surface of the sleeve base. The electrodeposition coating contains an electrodepositable resin and an electroconductivity-controlling powdery matter, which can be a powdery ceramic, with or without a powdery metal. A developing device for developing an electrostatic latent image and an image-forming apparatus including this developing sleeve are disclosed.
