Image forming apparatus

An image forming apparatus which forms an electrostatic latent image on a photosensitive member, develops the electrostatic latent image on the photosensitive member into a visible image by developer and transfers the visible image to a recording sheet, the image forming apparatus comprising:

• a conveying path that includes a first U shape portion at which the recording sheet moving from a recording sheet accommodating unit installed at a lower section of a housing toward one end of the housing turns in a U shape toward the other end of the housing;
• the conveying path conveying the recording sheet from the recording sheet accommodating unit via a region corresponding to the photosensitive member and then out of the housing;
• a registration roller that is disposed at an upstream position of the photosensitive member in the conveying path and regulates a tip end of the recording sheet moving toward the photosensitive member;
• and
• an inverting path that is a path along which the recording sheet returns from a downstream position of the photosensitive member in the conveying path to an upstream position of the registration roller in the conveying path, the inverting path including a second U shape portion joining with the upstream position of the registration roller,
• wherein the conveying path includes a downward slope portion that runs obliquely down from a topmost position of the first U shape portion toward a nipping position of the registration roller;
• and
• wherein the topmost position, a joining position in which the conveying path is connected to the inverting path and the nipping position get lower, in this order, in a vertical direction.
