A process unit comprising:
- a unit frame configured to be installable to an image forming apparatus by sliding in a predetermined direction, the unit frame including:
- a first side plate and a second side plate, the first side plate having through-holes, and
- a front beam and a rear beam, the front beam having a front-side grip and the rear beam having a rear-end grip, wherein a distance from an upper end of the front beam to an upper end of the front-side grip is smaller than a distance from an upper end of the rear beam to an upper end of the rear grip;
- and
- a plurality of cartridges disposed between the first side plate and the second side plate and detachably installable to the unit frame, each of the plurality of cartridges having:
- a developing roller rotatable about an axis;
- and
- a coupling gear for receiving a driving force to rotate the developing roller, the coupling gear being exposed outside via the through-hole.
A process unit comprising:
- a unit frame configured to be installable to an image forming apparatus by sliding in a predetermined direction, the unit frame including a first side plate and a second side plate, the first side plate having through-holes;
- a plurality of photosensitive drums, the unit frame supporting the plurality of photosensitive drums to be rotatable, wherein a rotating axis of each of the plurality of photosensitive drums is perpendicular to the predetermined direction;
- and
- a plurality of cartridges disposed between the first side plate and the second side plate and detachably installable to the unit frame, each of the plurality of cartridges having:
- a developing roller rotatable about an axis;
- and
- a coupling gear for receiving a driving force to rotate the developing roller, the coupling gear being exposed outside via the through-hole.
