A metal frame of an image forming apparatus including an image forming unit which forms an image on a sheet, comprising:

Metal frame of image forming apparatus and image forming apparatus

A metal frame of an image forming apparatus includes first and second sheet metal in which the first sheet metal includes a first engaging portion which is provided between first and second plate portions of the first sheet metal and is bent away from the first plate portion in the plate thickness direction of the first plate portion, wherein the first plate portion, the second plate portion, and the first engaging portion are formed integrally with each other. The second sheet metal includes a third plate portion with which the first engaging portion engages and a second engaging portion which is bent away from the third plate portion in a plate thickness direction of the third plate portion and engages with the first plate portion, wherein the second engaging portion is adjacent to the third plate portion. The second sheet metal further includes a third engaging portion which is bent away from the third plate portion and engages with the second plate portion, the third engaging portion being adjacent to the third plate portion. The third plate portion, the second engaging portion, and the third engaging portion are formed integrally with each other.

A metal frame of an image forming apparatus includes first and second spaced-apart supports which together support an image forming unit of the image forming apparatus. The second support includes first and second metal sheets wherein the first sheet metal includes a first flat surface portion in which a through-hole is formed and a bent and raised portion which is bent and raised from the first flat surface portion at a position adjacent to the through-hole, and wherein the second sheet metal is supported to the first sheet metal and includes a second flat surface portion which is sandwiched between the first flat surface portion and the bent and raised portion, and a protruded portion which protrudes from the second flat surface portion in a plate thickness direction of the second flat surface portion at a position overlapping with the through-hole in a vertical direction.
