Abstract: An image forming apparatus includes a fixing device to fix a toner image onto a recording material. The fixing device includes a heating unit, a pressure rotating member, a temperature detection unit, a storage unit, a reading unit, a sheet feeding unit, a conveyance unit, and a control unit. The pressure rotating member abuts the heating unit to form a nip portion. The storage unit stores information regarding a temperature rise rate of the fixing device. When the recording material is conveyed to the nip portion, the control unit controls the heating unit at a target temperature. Where a predetermined temperature lower than the target temperature is reached, the control unit controls the conveyance unit to start conveying the recording material from the sheet feeding unit to the nip portion. The control unit further determines the predetermined temperature based on the information read by the reading unit.
