<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of avoiding sudden toner supply, stably supplying a toner within a predetermined period of time, and minimizing effect on image density, thereby preventing the deterioration of image quality. <P>SOLUTION: In the image forming apparatus, a quantity of toner required to be supplied is divided in blocks and supplied over a predetermined number of times. In this case, based on the length of time that the toner can be supplied and the quantity of toner required to be supplied, the apparatus causes a pulse generating section 621 to generate a pulse for actuating a driving speed calculated by a drive speed calculating section 620. Thereby, the apparatus drives a buffer motor 601 and supplies the toner. <P>COPYRIGHT: (C)2009,JPO&INPIT |
