A Cessna 182 was proceeding direct to DRK at 9000. At the time; I believed the highest upcoming Minimum IFR Altitude (MIA) to be 9000 feet. I likely believed this because I misread the MIA chart that showed it to be 9900 feet. As the aircraft approached the area with the 9900 MIA; Albuquerque center called me asking if the aircraft could accept higher. At this point; I saw my mistake and immediately climbed the aircraft to 10000 feet. However; the aircraft was too close the area with the 9900 MIA; and entered it while still climbing to 10000 feet. The aircraft spent a few radar hits in the area before reaching 10000 feet.I should have payed closer attention to the MIA chart to verify what altitude would be required. Upon entering the area; I should have issued a terrain alert to the pilot.
ZLA ARTCC reported misreading Minimum IFR Altitude chart; contributing to an aircraft flying below the Minimum IFR Altitude.
