Abstract

A photoconductor unit includes a photoconductor and an electrode. The photoconductor includes a base member that is cylindrical and has a hardness that decreases with increasing distance from a first end toward a second end in an axial direction, and a photosensitive layer formed on an outer peripheral surface of the base member. The electrode is in contact with an inner peripheral surface of an open end portion of the base member at the first end.

First claim

What is claimed is:

1. A photoconductor unit comprising:
a photoconductor including
a base member that is cylindrical, and
a photosensitive layer formed on an outer peripheral surface of the base member; and

an electrode that is in contact with an inner peripheral surface of an open end portion of the base member at an end that is closer to a shock line than the other end is, the shock like being formed on the outer peripheral surface of the base member.

2. The photoconductor unit according to claim 1 , wherein a wall thickness of the base member is approximately 400 μm or less.

3. The photoconductor unit according to claim 2 , wherein the wall thickness of the base member is approximately 100 μm or greater.

4. A process cartridge comprising:
the photoconductor unit according to claim 1 ; and
a charging unit that charges a surface of the photoconductor included in the photoconductor unit.

5. An image forming apparatus comprising:
the photoconductor unit according to claim 1 ;
a charging unit that charges a surface of the photoconductor included in the photoconductor unit;
an electrostatic-latent-image-forming unit that forms an electrostatic latent image on the charged surface of the photoconductor;
a developing unit that develops the electrostatic latent image formed on the surface of the photoconductor into a toner image by using developer containing toner; and
a transfer unit that transfers the toner image onto a transfer object.
