Electrophotographic apparatus

An electrophotographic apparatus comprising:

• an electrophotographic photosensitive member;
• a charging unit configured to charge a surface of the electrophotographic photosensitive member;
• an image exposing unit configured to irradiate the charged surface of the electrophotographic photosensitive member with image exposure light to form an electrostatic latent image on the surface of the electrophotographic photosensitive member;
• a developing unit, which includes a toner, and which is configured to develop the electrostatic latent image with the toner to form a toner image on the surface of the electrophotographic photosensitive member;
• a transfer unit configured to transfer the toner image from the surface of the electrophotographic photosensitive member onto a transfer material;
• and
• a cleaning unit configured to remove a residual toner remaining on the surface of the electrophotographic photosensitive member after the toner image is transferred from the surface of the electrophotographic photosensitive member onto the transfer material,
• wherein the electrophotographic photosensitive member includes a surface layer containing a compound represented by the following formula (A), a binder resin, and silicon atom-containing particles,
• wherein the silicon atom-containing particles are one of silica particles or silicone resin particles, and
• wherein the toner includes toner particles each containing a polyester resin having a polyethylene terephthalate segment:
• in the formula (A), a1 to a6 each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a dialkylamino group, or a substituted or unsubstituted aryl group, or may be bonded to each other to form a ring structure, b1 to b5, c1 to c5, and d1 to d5 each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a dialkylamino group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aryloxy group, or a substituted or unsubstituted arylthio group, or may be bonded to each other to form a ring structure, and Ar1 and Ar2 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted heterocyclic group, or may be bonded to each other to form a ring structure, provided that Ar1 and Ar2 are prevented from both representing hydrogen atoms.
