Patent ID: 8585038

Claim:
An image-forming device comprising: a first sensor configured to detect a recording sheet manually inserted from a manual sheet insertion opening; an image forming portion configured to form an image on the recording sheet; a sheet-skew correction roller configured to correct skew of the recording sheet and convey the recording sheet to the image forming portion in a conveying direction, the sheet-skew correction roller being provided on a downstream side of the first sensor in the conveying direction; and a controller configured to control the sheet-skew correction roller to begin rotating if a stopping time has elapsed from a moment when the first sensor detects the recording sheet, wherein the stopping time is initially set to a first stopping time, the controller being configured to function as: a determining unit configured to determine whether the recording sheet is properly conveyed or is not properly conveyed, wherein the determining unit is configured to determine that the recording sheet is properly conveyed when the first sensor does not detect an absence of the recording sheet before the first stopping time has elapsed from the moment when the first sensor detects the recording sheet, and wherein the determining unit is configured to determine that the recording sheet is not properly conveyed when the first sensor detects an absence of the recording sheet before the first stopping time has elapsed from the moment when the first sensor detects the recording sheet; and a changing unit configured to change the stopping time to a second stopping time from the first stopping time if the determining unit determines that the recording sheet is not properly conveyed, the second stopping time being longer than the first stopping time.
