Paper feeding device and image forming apparatus

A paper feeding device comprising:

• a bearing base to which a spool inserted into a paper roll, around which a paper is wound, is detachably attachable;
• a support including:
• a leading-end detection sensor configured to detect a leading end of the paper on the paper roll and output a sensor signal;
• and
• a roller at a position in the support different from the leading-end detection sensor in a circumferential direction of the paper roll,
• wherein the support is configured to
• cause the leading-end detection sensor and the roller to contact a surface of the paper roll attached to the bearing base;
• and
• cause the leading-end detection sensor and the roller to be directed toward an axial center of the spool;
• a motor configured to rotate the spool in a feeding direction to feed the paper and in a reverse direction opposite to the feeding direction;
• and
• circuitry configured to:
• acquire the sensor signal from the leading-end detection sensor to control a feeding of the paper;
• determine whether the leading-end detection sensor detects the leading end of the paper based on the sensor signal of the leading-end detection sensor;
• and
• determine whether the paper roll is on the spool based on the sensor signal of the leading-end detection sensor.
