Abstract:
An image forming apparatus includes: a housing in which a light source, a laser scanning member, a light detecting portion configured to detect light incident on a predetermined position in a scanning path of the light scanned by the laser scanning member, and a scanning lens configured to cause the light scanned by the laser scanning member to be scanned at an equal speed on an image carrier, are disposed; a temperature gradient detecting portion, configured to detect a temperature gradient of the housing, a heater configured to heat the image carrier or a sheet; and a correction processing portion configured to correct the emission start timing based on the temperature detected by the temperature gradient detecting portion, and a predetermined expression, and change content of the expression based on an operation state of the heater at a start of an image formation process.

Claim (Index 5):
The image forming apparatus according to  claim 4 , wherein\n the correction processing portion calculates a shift amount d 1  of the emission start timing based on a following equation (1), wherein T 0  denotes a temperature detected by the first temperature detecting portion at a predetermined reference time, T 1  denotes a current temperature detected by the first temperature detecting portion, T 2  denotes a current temperature detected by the second temperature detecting portion, d 1  denotes the shift amount of the emission start timing, and K 1  and K 2  denote predetermined coefficients:\n d 1= K 1*( T 1\u2212 T 2)+ K 2*( T 1\u2212 T 0)\u2003\u2003(1).
