ABSTRACT:
A positioning mechanism for positioning a developing apparatus is disclosed. The positioning mechanism includes a base. A guide slot is formed on the base for guiding the developing apparatus to slide inside the base in a first direction. The base includes a first end and a second end. The lock mechanism further includes a positioning roller disposed on a first side of the guide slot for pressing the developing apparatus when the developing apparatus is inserted inside the base completely so that a first end of the developing apparatus contacts against the first end of the base and a second end of the developing apparatus contacts against the second end of the base.
