A printing device and parts therefor

摘要

A developing apparatus is provided. The apparatus (110) comprises a developing carrier (112), spaced apart from an image carrier (122) at a predetermined interval (G), for developing an electrostatic latent image formed on the image carrier (122) during rotation; and a rotational member (131), rotatably installed adjacent to the image carrier (122), for generating an air stream reverse to that generated by rotation of both the image carrier (122) and the developer carrier (112), thereby inhibiting a developer (22) from being scattered.
