Abstract
Disclosed is a developing process using a two-component type developer comprising a magnetic carrier and a toner, in which the developing conditions of the two-component type developer, that is, the composition and density of the developer in a distance between a photosensitive material drum and a developing sleeve (or a distance of a developing zone), are specified based on relations of these conditions to this distance. According to this developing process, the flowability of the developer in the developing zone is improved, and furthermore, the transferability of the toner to the photosensitive material drum is improved.
