The resin frame includes a base having a supporting surface that supports the image forming unit, a guide portion that extends in the base in an insertion direction in which the image forming unit is inserted along the supporting surface and that guides the image forming unit in the insertion direction while limiting movement of the image forming unit in an orthogonal direction that is orthogonal to the insertion direction, and a side plate portion that is provided at a peripheral edge of the base so as to extend in a direction perpendicular to the supporting surface, the base, the guide portion, and the side plate portion being integrally molded from a resin. A mold opening direction of a mold for molding the guide portion is set to a direction parallel to the orthogonal direction, and downstream end portions of the side plate portion in the mold opening direction are integrally connected to each other and extend essentially parallel to the perimeter of the base.

摘要： In a registration step, the temperature near a polygon mirror (83) is detected by a first temperature sensor (85), and the internal ambient temperature of an image forming apparatus (1) is detected by a second temperature sensor (86). Also, a registration adjustment value of each color is determined and stored in a memory (75). In a printing step, the registration adjustment value (A) of each color determined in the registration step is corrected based on a change in the temperature near the polygon mirror (83) and a change in the internal ambient temperature of the image forming apparatus (1). Furthermore, the write timing of an electrostatic latent image onto each photosensitive drum (13) by an optical scanning device (11) is controlled. Then, the position of the electrostatic latent image on each photosensitive drum (13) is shifted by an amount corresponding to the corrected registration adjustment value.

摘要： Multiple photoconductive drums on which images with different color components are formed respectively are rotated using individual motors, multiple adjustment images are formed at a predetermined interval along the cycle length of one rotation of each photoconductive drum, the reference phases for the rotation of the respective photoconductive drums are determined based on the maximum portions of the divergences between the predetermined interval and the detection interval of each adjustment image, and the individual motors are controlled so that the respective reference phases determined are aligned. The image forming region corresponding to the cycle length of one rotation of the photoconductive drum is divided into four or more even numbered regions, the, divergence amount of each region is calculated, and the maximum portions of the divergences are determined based on the difference between the divergence amounts of the divided regions being away from each other by a half cycle length.
