摘要： An image forming apparatus includes a control unit. The control unit is capable of executing a first mode for forming a toner image on the photosensitive member that rotates at a first speed and a second mode for forming a toner image on the photosensitive member that rotates at a second speed slower than the first speed, and the control unit causes the light illumination unit to perform the weak exposure in the first mode without thinning the scanning surface of the deflection scanning unit and perform the weak exposure in the second mode while thinning the scanning surface of the deflection scanning unit.

摘要： An image forming apparatus includes feeding, conveying, and separating members, and detecting, image forming, and control units. The feeding member feeds a recording material placed on a tray. The separating member and the conveying member separate recording materials at a nip. The detecting unit detects that the recording materials have been fed to the nip. The image forming unit forms an image on fed recording material. The control unit switches between a first and second control. Under the first control, the feeding member starts feeding a recording material placed on the tray, and ends feeding before a recording material trailing end passes through the feeding member. Under the second control, the feeding member starts feeding a recording material placed on the tray, and ends feeding after a recording material trailing end passes through the feeding member when the detection unit detects that the recording materials are fed to the nip.
