Title: IMAGE FORMING DEVICE
Abstract:
This image forming device (10) is characterized in that upon detecting that there is no paper in a cassette (130a) during image formation, the image forming device (10) is capable of continuing image formation by switching to another cassette (130b), and when it is determined based on a signal from a paper detection sensor (131a) in the cassette currently being used that there is no paper therein after light exposure has begun on the basis of the image data for a certain page, a secondary transfer roller (106) is cleaned and light exposure is initiated based on the image data for the page of interest before cleaning ends.
