IMAGE FORMING APPARATUS EMPLOYING MEDIA DETECTING DEVICE AND IMAGE OUTPUT METHOD OF THE SAME

摘要

An image forming apparatus employing a medium detecting device and an image output method thereof are provided to obtain outline shape information of a fed print medium and measure standards, skew quantity and shift quantity of the print medium based on the obtained information, thereby forming an image on an accurate location of the print medium. A medium supply unit(31,32,33) supplies a laminated print medium(30) through a transfer path. An image forming unit(10) forms an image for the supplied print medium. A medium detecting device(100) comprises a detecting unit and a determining unit. The detecting unit is disposed on the transfer path and detects outline shape information of the fed print medium. The determining unit determines standards and feeding information of the print medium based on the outline shape information of the print medium detected by the detecting unit.
