Claim 4:
5. The image forming apparatus according to claim 1, further comprising:
a first tray configured to support a first sheet;
a first pickup roller configured to picking up the first sheet in the first tray;
a first feeding clutch having a connected state in which the driving force of the main motor is transmittable to the first pickup roller and a disconnected state in which the driving force is not transmitted to the first pickup roller;
a second tray configured to support a second sheet;
a second pickup roller picking up the second sheet in the second tray;
a second feeding clutch having a connected state in which the driving force of the main motor is transmittable to the second pickup roller and a disconnected state in which the driving force is not transmitted to the second pickup roller; and
a sheet sensor configured to detect that the first sheet or the second sheet passes through a given position upstream of the photosensitive drum in a sheet conveying direction,
wherein the first tray and the second tray are disposed at positions where a distance from the second pickup roller to the sheet sensor is longer than a distance from the first pickup roller to the sheet sensor, and
wherein in a case where the first sheet is conveyed from the first tray, the controller sets the driving mechanism into the connected state at a timing when a first standby time elapses since the first feeding clutch is set to the connected state, and, wherein in a case where the second sheet is conveyed from the second tray, the controller set the driving mechanism into the connected state at a timing when a second standby time longer than the first standby time elapses since the second feeding clutch is set to the connected state.
