  • Patent number: 10927887
    Abstract: A resin coating layer has a shape line that indicates the shape of a surface and is divided by virtual straight lines parallel to the X axis and setting an area of recessed sections that protrudes below the virtual straight lines and an area of protruding sections that protrudes above the virtual straight lines. A virtual straight line at a position at which the area totals for the area of recessed sections and the area of protruding sections are equal is defined as the average line for unevenness. Areas that protrude downwards from this average line for unevenness are defined as recessed sections and areas that protrude above this average line for unevenness are defined as protruding sections. The average area Sa for one recessed section is 4-120 ?m2 and the number M of recessed sections between two points having a distance of 1 mm therebetween is 3-20.

  • Patent number: 10769507
    Abstract: An image forming apparatus includes a conveyor, a sensor, and control circuitry. The conveyor is configured to convey a sheet. The sensor is configured to detect the sheet conveyed by the conveyor. The control circuitry is configured to cause the conveyor to eject the sheet without stopping conveyance of the sheet and prohibit recovery printing when a size of the sheet determined based on detection of the sheet by the sensor is different from a setting size in a first operation mode. The control circuitry is configured to cause the conveyor to stop conveyance of the sheet and allow recovery printing when the size of the sheet is different from the setting size in a second operation mode in which a number of times of printing is larger than a number of times of printing in the first operation mode.
