An image forming apparatus acquires shape data indicating a shape of a specific sheet conveyed along a conveying path, masks, using the acquired shape data, a stick-out area that sticks out from a sheet area included in the shape data out of specific image data whose size in a first direction corresponding to a conveying direction of a sheet is larger than that of the sheet area, and forms, on the specific sheet, an image that shows a boundary between a mask area and a non-mask area opposing each other along the first direction out of the specific image data in which the stick-out area has been masked.

A printing apparatus including a head; a conveyor; and a controller. The controller is configured to execute: a first obtaining process of obtaining information on drying risk of an ink; and a printing process. A partial image includes an overlap image and a non-overlap image. The controller is configured to execute a second obtaining process of obtaining, based on the information on the drying risk, a first or second mask pattern as a mask pattern of a mask to be applied to image data of the overlap image. A number of a mask part of the second mask pattern with respect to an end part, of the overlap image, located away from the non-overlap image is smaller than a number of the mask part of the first mask pattern with respect to the end part.

A liquid ejecting apparatus includes: first and second ejection heads; a conveyor; a carriage; and a controller. The controller is configured to execute: a risk obtaining process of obtaining information on drying risk of a liquid; a mask selecting process of selecting one mask of a plurality of masks depending on the drying risk; and a printing process. Each of the plurality of masks defines first and second ratios. The first ratio is a ratio of increasing toward a first side in a conveyance direction of a first use-permission rate. The second ratio is a ratio of decreasing toward the first side in the conveyance direction of a second use-permission rate. The first ratio is different from each other among the plurality of masks, and the second ratio is different from each other among the plurality of masks.
