US 2013/0256969 A1 · IMAGE FORMING APPARATUS AND POST-PROCESSING METHOD

Abstract

An image forming apparatus includes a punching time measuring unit, a stapling time estimating unit, and a sheet-bundle interval time setting unit. The punching time measuring unit measures a punching processing time to perform punching processing. The stapling time estimating unit calculates an estimated stapling processing time to perform stapling processing by using the punching processing time measured by the punching time measuring unit. The sheet-bundle interval time setting unit sets a sheet-bundle interval time, which is a time from when the last sheet forming a sheet bundle subjected to the punching processing is fed until when the first sheet forming a subsequent sheet bundle subjected to the punching processing is fed.

Dependent claims

An image forming apparatus comprising:

a post-processing device configured to perform punching processing on a sheet on which an image is formed and stapling processing on a sheet bundle consisting of a plurality of punched sheets;
a punching time measuring unit configured to measure a punching processing time to perform the punching processing;
a stapling time estimating unit configured to calculate an estimated stapling processing time to perform stapling processing by using the punching processing time measured by the punching time measuring unit;
and
a sheet-bundle interval time setting unit configured to set, by using the estimated stapling processing time, a sheet-bundle interval time, which is a time from when the last sheet forming a sheet bundle subjected to the punching processing is fed until when the first sheet forming a subsequent sheet bundle subjected to the punching processing is fed.
