Abstract
A control method is provided for sheet-feeding in an image forming apparatus in which a sheet is fed to an image forming section of the image forming apparatus having a finisher which receives the sheet on which the image is formed and finishes the sheet. The control method includes the steps of: conducting a continuous image forming process that makes plural sets of sheets each on which the image has been formed; and controlling a starting of a sheet-feeder which feeds a first sheet of a set of sheets to the image forming section, according to a logical product of a condition on the continuous image forming process in the image forming apparatus and a condition of an operating process in the finisher.

A control method of sheet-feeding in an image forming apparatus in which a sheet is fed to an image forming section of the image forming apparatus having a finisher which receives the sheet on which the image is formed and finishes the sheet, the control method comprising the steps of:
- conducting a continuous image forming process that makes plural sets of sheets each on which the image has been formed;
- and
- controlling a starting of a sheet-feeder which feeds a first sheet of a set of sheets to the image forming section, according to a logical product of a condition on the continuous image forming process in the image forming apparatus and a condition of an operating process in the finisher.
An image forming apparatus comprising:
- (a) an image forming section for forming an image on a sheet;
- (b) a sheet storing section for storing a plurality of sheets;
- (c) a first sheet-feeder for feeding a sheet from the sheet storing section;
- (d) a second sheet-feeder for receiving the sheet fed from the first sheet-feeder and for feeding the sheet to the image forming section;
- (e) a finisher for finishing the sheet on which the image has been formed by the image forming section;
- and
- (f) a controller for controlling a sheet-feeding operation of the second sheet-feeder,
- wherein in a continuous image forming process for making plural sets of image-formed sheets each being subjected to a finishing operation by the finisher, the controller controls a starting of the second sheet-feeder that forms an interval between the sets, according to a logical product of;
- (1) time passing information established by a continuous interval timer that establishes an interval between each sheet,
- (2) information indicating that a sheet-feeding preparation in the second sheet-feeder is completed,
- (3) information indicating that an image formation in the image forming section is completed, and
- (4) information of a time passing from a conveyance starting of a first sheet fed by the second sheet-feeder that is established by a finishing time in the finisher.
