Abstract:
1. A developing unit comprising: a photoconductor to form an electrostatic latent image thereon; a developer roller to develop the electrostatic latent image into a visible toner image by applying toner to the photoconductor; a toner-supply roller to supply the toner to the developer roller; an agitator to agitate the toner to supply the toner to the toner-supply roller; a photoconductor gear formed on a side of the photoconductor, to be rotated by an external driving force; a developer roller gear formed on a side of the developer roller and engaged with the photoconductor gear to be rotated by the photoconductor gear; an idle gear engaged with the developer roller gear to be rotated by the developer roller gear; a toner-supply roller gear formed on a side of the toner-supply roller and engaged with the idle gear to be rotated by the idle gear; and an agitator gear formed on a side of the agitator and engaged with the toner-supply roller gear to be rotated by the toner-supply roller gear.
