Abstract: PROBLEM TO BE SOLVED: To enable free selection between a high image quality mode using a toner of a low coloration degree and an image quality mode using a toner of an ordinary coloration degree without increasing a development device or a photoreceptor. SOLUTION: When a toner end is not applicable (NO in S3) and the current toner is different from the previous toner cartridge (YES in S4), it is determined whether or not the user selection mode is the image quality priority mode. When the image quality priority mode is selected (YES in S5), the toner discharge mode is performed (S6), and after the discharge, the toner replenishment mode is performed. In the discharge mode, a consumption pattern is created on the photoreceptor, and the toner on the photoreceptor is cleaned (S7). In the discharge mode, the toner is discharged to the toner end level (YES in S8), and a toner is replenished (S9). Then, the concentration adjustment mode is performed (S10) to complete the sequence. COPYRIGHT: (C)2010,JPO&INPIT
