IMAGE FORMING APPARATUS

摘要

An image forming apparatus is provided. The image forming apparatus, in a case in which a toner on a transfer belt is checked through a sensing unit, is capable of preventing a rotation of a guide roller, which is configured to guide the transfer belt, by use of a regulation device, so that a check error occurring due to vibration of the guide roller is reduced. Thus, the toner on the transfer belt is checked with increased accuracy and precision.
