Abstract
An image forming apparatus includes an image forming station for forming an image, a registration member, a registration motor, and a fixing unit. The registration member is configured to feed the recording medium in appropriate timing such that a recording medium is aligned with the toner image formed in the image forming station. The registration motor is configured to drive the registration member. The fixing unit is configured to fix the toner image on the recording medium and includes a rotary heating member to heat the recording medium, a rotary pressure member to contact and press against the heating member forming a fixing nip portion where the heating roller and the pressure roller meet, and a sheet separator to eject air to separate the recording medium from the rotary heating member based on a drive signal of the registration motor.
