摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus that reliably ejects paper P remaining in an image forming apparatus. SOLUTION: The image forming apparatus 100 includes: an ejection/inversion roller 21 that ejects paper P out of the apparatus or inverts the paper P within the apparatus; a one-sided conveyance path 43 formed from a paper feed path for feeding paper P to a secondary transfer section 34 and a conveyance path along which paper P passed through the secondary transfer section 34 is conveyed to the ejection/inversion roller 21; and a both-sided conveyance path 44 along which paper P inverted by the ejection/inversion roller 21 is conveyed to the one-sided conveyance path 43. If the paper P remaining on the one-sided conveyance path 43 is not detected by detection sensors 53, 54, and 55 when the image forming apparatus 100 is started or it is re-started after jam detection, conveying rollers 40 and 41 and a resist roller 19 are rotated. Thus, a conveying operation using both-sided conveyance path 44 is started and then the ejection/inversion roller 21 is rotated to perform an ejecting operation in the one-sided conveyance path 43.

摘要： PROBLEM TO BE SOLVED: To reduce shift in image forming position which depends on the light quantity of a light beam. SOLUTION: In an image forming apparatus where the light quantity of a light beam being used for forming a latent image is switched depending on the difference of resolution, lasers 101 to 104 emit a light beam for forming a latent image on a photosensitive drum 203. A light beam thus emitted is used for scanning by a polygon mirror 105 and the scanned light beam is detected by a BD sensor 106. When controlling the emission timing of the lasers 101 to 104 depending on the timing the light beam is detected, a timing control section 204 selects a suitable emission timing from a table in a storage 205 depending on the light quantity of the light beam or the resolution.
