Abstract:
1. An apparatus that controls a laser scanning unit in an electro-photographic image forming apparatus in which an installed developer forms an image by developing a result obtained by driving the laser scanning unit, the laser scanning unit control apparatus comprising: a sensing unit that senses whether the developer is installed and whether a cover of the image forming apparatus is closed; an examining unit that provides an examination result based on whether a condition is met wherein both the developer is installed and the cover is closed as sensed by the sensing unit; and a laser scanning unit driver that drives the laser scanning unit and that is switched to selectively drive or not drive the laser scanning unit in response to the examination result, wherein the laser scanning unit driver comprises: a first switching unit that is switched in response to whether the developer is installed; and a second switching unit that is switched in response to the examination result, wherein when the second switching unit is closed, the laser scanning unit is driven through the closed first switching unit.
