PROBLEM TO BE SOLVED: To perform residual quantity detection of developer without being limited to perform during an image formation. SOLUTION: As for this electrophotographic image forming device, a controlling process for the image density stabilization is performed (S102), and a fine adjustment process for the half tone image is performed (S103). At this time, the developer residual quantity detection is simultaneously performed (S104), and the developer residual quantity is notified, after the fine adjustment of half tone image. Thereafter, the device becomes a standby state (S105), and waits for the print indicating signal (S106). On accepting the printing indication signal, the device performs printing (S107), to compute the developer residual quantity, to inform it (S108), and returns to the standby state. |
