An image forming apparatus includes an image forming section configured to form an image on a recording paper sheet and a housing accommodating the image forming section. The housing includes: an enclosed and bottomed housing body having an enclosed sidewall and a bottom formed continuously and integrally with the sidewall; and a lid removably attached to the housing body to cover an opening of the housing body. The image forming section is separate from the housing body and is placed on top of the bottom in the housing body. When the lid is removed from the image forming apparatus and the image forming section is lifted above the opening, the image forming section is taken out of the housing body through the opening and the housing body is removed from the image forming apparatus.
