Title:
DEVELOPER SUPPLY DEVICE, DEVELOPER SUPPLY CONTROL METHOD, AND DEVELOPER SUPPLY CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2007/091507
Kind Code:
A1
Abstract:
An image forming device in which the toner density of a two-component developing device
can be stably controlled in printing a one-page image and the frequency of interruption
of even printing a series of pages can be decreased as less as possible. The number
of pixels of the image relevant to the development counted during the printing
and the toner consumption is estimated from other image information, and the
amount of toner corresponding to the consumption is supplemented. In this supplement,
the count is acquired at an intermediate time of the one-page printing, the toner
consumption is estimated, and the toner is supplemented during the printing
after the intermediate time. Thereby, toner supplement can be performed ahead
of its schedule, and a variation of the toner density can be prevented correspondingly.
