Abstract

An image forming apparatus includes a sheet size sensing portion, an image forming portion, a registered condition information acquisition portion, and a printing control portion. The sheet size sensing portion senses the size of a sheet material in a sheet receptacle. The registered condition information acquisition portion acquires registered condition information representing the correspondence relationship between the size of the sheet material and a printing condition. The printing control portion causes the image forming portion to execute a printing process in accordance with the printing condition corresponding to the size sensed by the sheet size sensing portion in the registered condition information.

First claim

1 . An image forming apparatus comprising:
a sheet size sensing portion configured to sense a size of a sheet material placed on a sheet receptacle; an image forming portion configured to execute a printing process of forming an image on the sheet material fed from the sheet receptacle; a registered condition information acquisition portion configured to acquire registered condition information, representing a correspondence relationship between the size of the sheet material and a printing condition, from a non-transitory computer-readable first storage portion configured to store the registered condition information in advance; and a printing control portion configured to cause the image forming portion to execute the printing process in accordance with the printing condition corresponding to the size sensed by the sheet size sensing portion in the registered condition information.

2 . The image forming apparatus according to claim 1 , further comprising:
a valid period information acquisition portion configured to acquire valid period information, representing an enabling period during which printing based on the registered condition information is enabled, from a second non-transitory computer-readable storage portion that stores the valid period information in advance; and a first selection portion configured to select whether or not to cause the image forming portion to execute the printing process in accordance with the printing condition in the registered condition information, depending on whether or not a time point before printing starts is within the enabling period in the valid period information.

3 . The image forming apparatus according to claim 2 , further comprising an enabling period revision portion configured to extend or shorten the enabling period in the valid period information, depending on whether or not a feeding status of the sheet material from the sheet receptacle satisfies a predetermined extension condition or shortening condition.

4 . The image forming apparatus according to claim 1 , further comprising:
an input portion configured to input user identification information; a valid user information acquisition portion configured to acquire valid user information, including the user identification information and representing a user for which printing based on the registered condition information is enabled or disabled, from a non-transitory computer-readable third storage portion that stores the valid user information in advance; and a second selection portion configured to select whether or not to cause the image forming portion to execute the printing process in accordance with the printing condition in the registered condition information, depending on whether the user identification information obtained through the input portion is information representing the enabled user or information representing the disabled user in the valid user information.

5 . The image forming apparatus according to claim 1 , further comprising
an input portion configured to input user identification information, wherein the registered condition information acquisition portion is configured to acquire, from the first storage portion that stores the registered condition information representing the correspondence relationship between the size of the sheet material and the printing condition for each one of the user identification information, the registered condition information corresponding to the user identification information obtained through the input portion.

6 . The image forming apparatus according to claim 1 , further comprising
a size change determination portion configured to determine presence or absence of any changes in a size sensed by the sheet size sensing portion, every time the sheet material is fed from the sheet receptacle to the image forming portion, wherein the printing control portion is configured to, every time the size sensed by the sheet size sensing portion changes, cause the image forming portion to execute the printing process in accordance with the printing condition corresponding to the sensed size that has been changed.
