发明名称 IMAGE FORMING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus reducing a downtime by urging a user to reattach a toner container without stopping an operation if the attachment of the toner container is in a failure when the toner container is replaced. <P>SOLUTION: The image forming apparatus includes: a toner bottle 1 attached so as to be detachable; a drive motor 101 that rotates and drives the toner bottle 1; a current detecting circuit 150 that detects a driving state of the drive motor 101; and a magnetic sensor 161 that detects the attaching of the toner bottle 1. Based on the detection results of the current detecting circuit 150 and the magnetic sensor 161, a CPU 152 determines a failure in the attaching of the toner bottle 1. If it is determined that the attachment of the toner bottle 1 is in a failure, an instruction is shown on a display unit to urge reattaching of the toner bottle 1. <P>COPYRIGHT: (C)2009,JPO&INPIT
