Abstract
An image forming unit includes a cartridge and a unit frame. The cartridge has a cartridge-grip. The unit frame is configured to accommodate the cartridge. The unit frame includes a first plate, a second plate, a first beam, and a second beam. The first plate has a through hole. The first beam extends between the first plate and the second plate. The first beam includes a frame-grip disposed between an upper end of the first beam and a lower end of the first beam. The second beam extends between the first plate and the second plate. When the cartridge is accommodated in the unit frame, a distance between the lower end of the first beam and an upper end of the frame-grip is smaller than a distance between the lower end of the first beam and an upper end of the cartridge-grip.
