PROBLEM TO BE SOLVED: To provide an elevator door controller which detects of ingress/egress of a passenger or loading/unloading of a load for automatic control of door closing operation. SOLUTION: A CPU 41 detects the load of a car after a door is opened and stores load data in a load data storage part 42. The CPU 41 reads a plurality of load data based on a control program preset in a program setting part 43 and computes a variation widthΔM in the load of the car from the data. When the variation widthΔM become a threshold value X or smaller preset in a threshold value setting part 44, the CPU 41 controls a door driving part 12 so that the door may be closed. The CPU 41 detects a load variation after the door is opened, and completion of ingress/egress of a passenger automatically for controlling the closing operation of the door, thus it is possible for a passenger to use the elevator comfortably.
