Image forming apparatus

摘要

An image forming apparatus has a chassis, an image forming section, a shield metal plate, and a plurality of substrates. The chassis has a first surface and a second surface on an opposite side to the first surface. The image forming section is disposed in an internal space formed between the first and second surfaces of the chassis and performs an image forming process on a sheet. The shield metal plate is provided vertically between the second surface and the image forming section and has a third surface facing a side of the first surface and a fourth surface facing a side of the second surface. The plurality of substrates are provided vertically on the third surface of the shield metal plate and have electrical components protruding toward the first surface.

主权项

1. An image forming apparatus, comprising:
a chassis having a first wall and a second wall opposite the first wall, the first wall and the second wall extending in a vertical direction, at least the second wall of the chassis being made from a resin material; an image forming section disposed in an internal space formed between the first and second walls of the chassis and performing an image forming process on a sheet; a shield metal plate provided vertically between the second wall and the image forming section and having a first surface facing toward the first wall and a second surface facing toward the second wall; a plurality of substrates provided vertically on the first surface of the shield metal plate and having electrical components protruding toward the first wall, a predetermined voltage being supplied to the electrical components; and a main body frame provided inside the chassis, the main body frame being made from a flame-retardant resin material having a flame-retardant grade higher than a flame retardant grade of the resin material of the second wall of the body, the main body frame supporting the image forming section and having a wall section disposed between the shield metal plate and the image forming section, the wall section extending in the vertical direction and facing the first surface of the shield metal plate so that the substrates are between the shield metal plate and the wall section.
